Study on Engineering Measures for the Improvement of Agroecological Environment in Beijing

Protection of agriecological environment is one of the most important requirements for sustainable development of agriculture. Some factors seriously influence ecological environment, such as the producing of agriculture waste and its harmfulness caused by improper treatment. The total area of Beijing is 16,800km². It is consist of urban area of 800km² and rural area of 16,000km², which is 95% of the total area. The agroecological environment of Beijing has two functions. First, it must produce grain, vegetable, oil, meat, egg and milk. Secondly, it has to dispose great amount of waste from agriculture, industry and daily life, to maintain and adjust the ecological system balance. The treatment and comprehensive utilization for these waste is related to many technical and engineering problems, and it is a new field of research in economy development. This article analy-sises and discusses the present situation of main agriculture waste in Beijing which includes crop straw, livestock and poultry manure, residual plastic in soil, the influence on ecological environment, capability of operation and engineering measures of disposition and utilization. The article aims at further dispose and utilize agriculture waste and continuously improve the agroecological environment quality, to maintain the sustainability of agriculture development.
