| 摘 要： | 太湖流域的水环境质量呈现严重恶化趋势,农业污染物的排放是太湖流域水体环境恶化的主要原因之一。农业污染物主要来源于种植业、畜禽养殖业和水产养殖业的生产过程,不同于以往分开论述三者对水环境的影响,本文基于全国第一次污染普查数据,运用污染足迹模型定量分析了湖州市农业面源(种植业、畜禽养殖业和水产养殖业)对水环境的影响。研究结果表明:(1)农业生产产生的污染物对水环境的影响排序为:磷>氮>有机物;(2)各农业生产类型对水环境的影响排序为:水产养殖业>种植业>畜禽养殖业;(3)湖州市各区县对水环境的影响也存在着明显的空间差异。通过对湖州市农业污染足迹评估,可以明确地提出哪种污染物类型、农业生产类型和区域是湖州市农业面源污染治理的重点。研究结果可以为太湖流域农业的可持续发展和水资源的可持续利用提供一定的参考价值。

| Abstract: | Agricultural production is considered one of the most important sources of water quality deterioration in the Taihu Lake Basin, China. Crop farming, livestock & poultry breeding and aquaculture are primary agricultural non-point sources and their impacts on the water environment are, in most cases, evaluated separately. Therefore, it is a challenge for current research to consider all of the different agricultural non-point sources as a whole and assess their combined influence on the water environment. The purpose of this paper is to evaluate the conjoint impact that agricultural non-point sources such as crop farming, livestock & poultry breeding and aquaculture have had on the local water environment in the Taihu Lake Basin by taking Huzhou City of Zhejiang Province as a case study. To achieve this, a new, innovative approach named the “Waste Absorption Footprint” (WAF) is applied. The results show that nitrogen and phosphorus pollution generated by agricultural production are more serious than that of organic substances, while aquaculture and crop farming are more critical pollution sources compared with livestock and poultry breeding, and so they should be the focus of environmental management and pollution control initiatives. There is a regional discrepancy in the spatial distribution of agricultural non-point source pollution across counties and districts, which provides information for determining the key regions for the treatment of agricultural pollution. This study demonstrates that the WAF method can make a comprehensive assessment of the influence of agricultural production on the water environment and provide references for the control and management of agricultural non-point source pollution, which is of great importance for management of the water environment. |
