灌区面源污染的评价方法研究

Study on the Evaluation Method of Non-point Source Pollution in Irrigation District

随着灌区生态节水建设的发展,灌区的面源污染程度的确定也越来越重要。通过对灌区面源污染定性的和定量的综合分析研究,可得到主观和客观综合的数据;通过AHP方法,对所得到的数据进行计算分析,最后可得出灌区面源污染程度的相应指数,从而定出灌区面源污染的等级,这为灌区建设计划的制定和实施提供很好的依据。

Along with the development of the zoology and water saving irrigation, the evaluation of the non-point pollution degree in irrigation district has become more and more important. Through qualitative and quantitative synthetical analysis of the non-point pollution in irrigation district, the subjective and external data can be gained. Then using the method of AHP to calculate and analyze the data, the corresponding index of the non-point pollution degree in irrigation district can be get to evaluate the rank of the non- point pollution in irrigation district . This will provide base for the establishment and implementation of the irrigation construction plan.
