Analysis on Spatial Pattern Changes of Land Resources Utilization and Soil Pollution Sources in the New Period

Abstract

Land use change is an important part of global change, and land use research has also become the focus of global change research. With the growth of population and the economic development of society, the relationship between human beings and land is getting closer and closer, and the interaction is getting stronger and stronger. The resources and environmental problems brought by it have also received strong attention from all walks of life. The use of change has become a major factor in environmental change. At present, environmental problems have become the key link in ecological problems, and in environmental problems, soil pollution is one of the major sources of pollution. Soil pollution can affect crop yields and even contaminate groundwater, so soil pollution has always been a key link in pollution prevention. This paper introduces the connotation and related theories of land resource utilization change, and analyzes the formation and classification of soil pollution sources and the problems of land resource space utilization in the new era. On the basis of reviewing the status quo of soil pollution in China, this paper analyzes the risk analysis and damage of soil pollution, and studies the spatial and temporal pattern change of land use and soil pollution control countermeasures in the new period. In recent years, China’s environmental problems have become increasingly prominent, including soil pollution is relatively serious, soil pollution has a certain uniqueness, relatively hidden, lagging and long-lasting, it will cause pollution to crops and food, which in turn affect people’s health and soil pollution. Not only does it affect humans through crops, but it can also enter the human body through direct contact or breathing, causing harm to the human body. The research and analysis in this paper is to achieve the sustainable use of land resources in the new era and to ensure that people have access to adequate and safe food and living environment.
