Abstract: Polar regions have a profound impact on global climate change, because polar regions are one of the world’s largest sources of cold. Sea ice is the main influencing factor in the polar regions, which has a great influence on the heat transfer, which in turn affects the global climate system. In the past two decades, Arctic sea ice has decreased year by year, while Antarctic sea ice has increased. The use of passive satellite remote sensing data for long-term observation and analysis of polar sea ice will provide an important theoretical basis for studying global climate change and an important data source for polar sea ice research. This study uses the data of the Antarctic and Arctic sea ice density data from 1998 to 2018 to compare and analyze the changes in time and space to find out the changes of the sea ice in the south and Arctic. Using the SSM / I data of the US National Defense Meteorological Satellite and the NASA TEAM algorithm, the sea ice data from 1998 to 2018 was compared and analyzed. The specific process is to use the NASA TEAM algorithm to invert the Arctic and Arctic sea ice, obtain multi-year ice, one-year ice, and overall sea ice density data, and then determine the sea ice area. Through comparative analysis, it is found that the area of Antarctic sea ice is significantly larger than that of the North Pole, and the change trend of the two is similar. The downward trend is greater than that of the South Pole; the total annual ice volume of the South Pole is greater than that of the North Pole, both of which have an upward trend, and the Arctic has a greater increase; the overall sea ice has fallen, and the multi-year ice has decreased while the annual ice has increased. Sea ice has a tendency to transform from multi-year ice to one-year ice; Antarctic multi-year ice is mainly distributed in the Weddell Sea, with stable areas accounting for 60% of the multi-year ice area; Antarctica is dominated by one-year ice, and one-year ice stable area accounts for one 80.1% of the total annual ice area; Arctic multi-year ice mainly exists in the central area of the Arctic Ocean. The Arctic multi-year ice stable area only accounts for 35.06%; the Arctic one-year ice is mainly distributed around the multi-year ice periphery, and the stable existence area accounts for the total annual ice area 48.5%.Abstract: Polar regions have a profound impact on global climate change, because polar regions are one of the world’s largest sources of cold.

Abstract: Phosphogypsum is a by-product of the wet process of phosphoric acid production. Although the main component of phosphogypsum is calcium sulfate, it also contains a variety of impurities harmful to the environment. How to economically and comprehensively utilize phosphogypsum to turn waste into treasure has become a global problem. Since the industrialization of wet process phosphoric acid, people have been studying the comprehensive utilization of phosphogypsum, including the direct utilization of phosphogypsum for impurity removal and the reuse of phosphogypsum after dissolution and transformation. At present, the treatment of phosphogypsum is not short of technology, but the profit of phosphogypsum treatment. Recent research has found that phosphogypsum can be completely dissolved by a chemical and metallurgical cycling process and transformed into calcium and sulfur products with market competitiveness and economic benefits. These include high-quality calcium sulfate dihydrate, light calcium carbonate, and gypsum whiskers with high added value. This is another step forward for the final solution to the problem of phosphogypsum stacking endangers environmental safety.Abstract: Phosphogypsum is a by-product of the wet process of phosphoric acid production.

Abstract: With the rapid development of modern industry, the types and emissions of heavy metal wastewater are also increasing day by day. Heavy metal wastewater is non biodegradable, and discharge standards are also updated and iterated with people's continuous requirements for health. Based on the current situation of industrial heavy metal wastewater treatment in China, this paper summarizes the sources and treatment status of heavy metal wastewater, as well as the commonly used technologies and processes for industrial wastewater treatment from traditional to modern at home and abroad, introduces the advantages and disadvantages of physical, chemical and biological treatment methods for industrial wastewater containing heavy metals in practical applications, and looks forward to the development trend of Advanced oxidation process and biological treatment methods. The biological treatment method has the characteristics of rich raw materials, environmentally friendly and pollution-free, but at present, the research on biotechnology is not mature and its application is not widespread. If the system is applied to industrial treatment of heavy metal wastewater, further research is still needed. There are few heavy metal wastewater treatment equipment or systems developed from heavy metal wastewater treatment processes, and the issues of continuous operation, automation, and large-scale treatment of heavy metal wastewater still need to be explored. There is also room for development in the field of resource development and utilization by extracting and recovering heavy metals from sludge after heavy metal wastewater treatment. This article reviews the methods for treating heavy metal wastewater and evaluates them, with the aim of pointing out research directions and providing practical application references for the large-scale industrial development of industrial heavy metal wastewater in the future.Abstract: With the rapid development of modern industry, the types and emissions of heavy metal wastewater are also increasing day by day.

Abstract: At present, China's saline-alkali soil area is very large. In the saline-alkali soil, the salinity will affect the growth of plants in the severe areas, so the plants cannot survive. How to maintain soil quality and prevent soil salt from being high has become an important research goal of soil improvement. Soil amendments can combine many small soil particles together to form large water stable aggregates. And it is widely used to prevent soil erosion, reduce soil water evaporation or excessive evaporation, save the amount of irrigation and promote the healthy growth of plants. This study through the use of homemade iron han ecological amendments, phosphogypsum, garden waste decay secondary materials, five materials mixed polyacrylamide and microbial amendments, combined with the water salt engineering comparison experiment, the whole experiment for three, respectively is composite amendments and water salt engineering comprehensive improvement measures (TG1, TG2), the traditional composite amendments (G 1, G 2) and tai tian shallow water conservancy salt project (T) single measures. In the above experiments, the best effects are TG 1 (comprehensive improvement measures of Tiehan ecological amendments) and TG 2 (comprehensive improvement measures of Heka amendments). Although the amount of reagent applied is different, the treatment effect is very good. The results show that different improvement measures significantly reduced the salt content and reduced the PH value of soil, and improved the soil nutrients. This measurement data provides a certain theoretical basis for the repair and study of salinized soil. It also shows that soil amendments have obvious guidance for the application of salinized soil.Abstract: At present, China's saline-alkali soil area is very large.

Abstract: The complex and diverse geological structure and extremely high degree of karst development in karst areas have led to severe soil erosion and fragile ecological environment, and plants are often exposed to severe drought stress. In this paper, we analyse the adaptation mechanisms of plants to the karst drought environment in terms of their morphological characteristics such as roots, stems and leaves, photosynthetic characteristics, metabolism and hormone regulation. It is found that plants in this region often exhibit morphological characteristics such as well-developed roots, fleshy stems and thick leaves under drought stress; in addition, plants in this region can maintain normal plant growth by regulating stomata opening, metabolic pathways and regulating hormone concentrations. Here we propose to improve the drought resistance of plants in karst regions through the selection and breeding of good seeds, optimization of soil environment, chemical and microbial regulation, etc. We discuss the problems in the current research and propose future research prospects to deepen the understanding of the ecological adaptation mechanisms of plants under drought stress in karst regions, with a view to providing scientific basis for the ecological restoration of vegetation and the selection and breeding of drought-tolerant and drought-resistant plants in the region.Abstract: The complex and diverse geological structure and extremely high degree of karst development in karst areas have led to severe soil erosion and fragile ecological environment, and plants are often exposed to severe drought stress.

Abstract: Short-term photovoltaic power generation prediction is of great significance for improving the stability of power system grid connection. In order to improve the accuracy of short-term photovoltaic power generation prediction, a prediction method is proposed based on integrated models. Firstly, the quartile method is used to detect whether there are outliers in the raw data, and then multiple feature variables that affect short-term photovoltaic power generation are selected by combining feature contribution and Pearson correlation coefficient. Secondly, construct the structure of the integrated model and use the k-fold cross validation method to train the models in the primary and secondary learners. It is a new feature of the secondary learner with the results of the primary learner. Finally, the effectiveness of this method was verified using actual datasets. The simulation results show that a primary learner with high compatibility with outliers is beneficial for improving the prediction accuracy of photovoltaic power generation. The combination of two feature selection methods can more effectively extract information from the original data and improve the generalization ability of the model compared to a single feature extraction method. Moreover, the integrated model can achieve higher prediction accuracy than a single model.Abstract: Short-term photovoltaic power generation prediction is of great significance for improving the stability of power system grid connection.
