农业污染减排指标体系初步构建

控制和削减农业污染物排放总量是国家环境保护"十二五"规划的重点工作之一,但现行的环境管理及产排污量削减与控制技术中还没有完整的农业污染减排的指标体系。该文阐述了构建农业污染减排指标体系的基本原则和方法,综合考虑不同农业生产类型污染物产排过程的特点,从种植业、畜禽养殖业和水产养殖业3个方面初步构建农业污染减排指标体系,以期为研究农业主要污染物减排核算体系的关键参数和制定减排核算技术方法提供基础性技术支持。基于当前农业污染减排实施中可能存在的问题,对指标体系的进一步完善提出了相关建议。

Preliminary Development of an Index System for Agricultural Pollution Reduction

Controlling and reducing the total amount of agricultural pollution is one of the top priorities of the energy saving and discharge reduction strategy during the Twelfth Five-Year Plan period of China.However,so far there is no such an index system in the current environment management and technology for agricultural pollution reduction.A rational and practical index system will help us to better understand the situation of agricultural pollution and promote agricultural pollution reduction.The basic principles and methods of developing an index system has been elucidated.Considering comprehensively characteristics of the production and discharge processes of different types of agricultural pollution,an index system for agricultural pollution reduction was preliminarily developed for planting,livestock and poultry breeding and aquaculture,in the hope that it would provide parameters key to the study on accounting systems for reduction of some major agricultural pollutants as well as some basic technical support for working out discharge reduction techniques and methods.Based on the problems that may exist in implementing the current agricultural pollution reduction strategies,relevant suggestions are brought forth to further consummate the index system.
