区域农业废弃物资源存量估算及利用现状

Study on Stock Estimation and Utilization Status of Agricultural Residue Resources at a County

选取安县柏杨村作为研究区域,结合实地调查和参考已有相关研究成果,确定研究区农业废弃物相关基础数据。确定研究区域农业废弃物资源基础数据、及量估算方法和各种估算参数。在此基础上,研究了区域农业废弃物资源利用现状及资源存量。结果表明:研究区农业废弃物资源种类多,地理分布差异明显;研究区农业废弃物资源存量大,2009年农业废弃物资源总的存量达3 415.44t,相当于901.06t标准煤及118 641.55m3沼气,具有较强的利用潜力;研究区农业废弃物资源综合利用率低,浪费量大,同时造成严重的环境污染。

On the basis of field investigation and reference to the results from correlative studies,the approaches and parameters of estimation of annual quantity of stock were defined.The study chose Boyang village in Anxian County as an example,and analyzed the status and the stock of agricultural residue utilization.The results showed that there were many agricultural residue types and a great of stock,but the geographical distribution was different in the research area.The stock of agricultural residue was 3 415.44 tons in 2009,corresponding to 901.06 tons of standard coal and 118 641.55 m3 of biogas.The study also pointed out that the comprehensive utilization rate of agricultural residue was comparatively low and the resources were wasted seriously,which led to serious pollution of the environment.
