Research on Environmental Risk Control of Highly Intensive Agricultural Land Use Based on Computer Technology and Landscape Scale

Abstract

Under the background of China's rigid population growth and the reduction of cultivated land area, the degree of agricultural intensification has been increasing. Pesticides and fertilizers have greatly increased crop yields. However, the large amount of agricultural chemicals input leads to the decline of soil and environmental quality. The environmental pollution caused by agricultural activities is increasing, especially in the high intensive agricultural areas with high land use intensity and a large amount of agricultural chemicals input. Agricultural land use is facing the dual challenges of ensuring food security and ecological environment security, which is an arduous and urgent task to realize the sustainable and healthy development of China's agricultural countryside. High intensive agriculture gains higher economic benefits, but it also leads to serious environmental consequences. In the face of the increasingly serious problems of agricultural ecological environment, how to guarantee the economic development and control the environmental risk of agricultural land use is an urgent practical problem. Based on this, this paper uses computer technology to analyze the environmental risk control strategy of highly intensive agricultural land use based on the landscape scale.
