湘江流域面积达九万平方公里。江水供我省长沙、株州、湘潭、衡阳市及沿岸城镇居民饮用。流域的水稻播种面积和粮食产量约占我省50%左右,是我省农业生产比较发达的粮食产区。随着农业生产的发展,复种指数与产量的提高,农药的使用量虵在逐年增加,造成了湘江水系和流域农药的残留污染。为了保证人民的健康,发展农业生产,七九年我们承担了省环办下达的“湘江流域农药污染源的研究”任务,我们选择了有代表性的长沙郊区大托公社大托大队进行重点调查研究,以取得经验,为80年全面展开工作作准备。下面是大托大队农药污染及其对湘江水系影响研究的情况汇报。
Xiangjiang River basin area of 90,000 square kilometers. Rivers for our province, Changsha, Zhuzhou, Xiangtan, Hengyang and coastal urban residents drinking. The sown area and grain yield of paddy fields account for about 50% of our province, which is the most developed grain producing area for agricultural production in our province. With the development of agricultural production, the index of multiple cropping and the increase of output, the use of pesticides has been increasing year by year, resulting in the residual pollution of the Xiang River water system and the pesticides in the basin. In order to ensure the health of the people and develop agricultural production, in 1979 we undertook the task of “Research on Pesticide Contamination Sources in the Xiangjiang River Basin” issued by the Provincial Central Government. We selected a representative group of Datuo caretakers of the Datuo commune in the suburb of Changsha to carry out the key investigations and studies In order to gain experience and prepare for a full 80-year work. The following is a report on the pesticide contamination of Datuo Brigade and its impact on the Xiangjiang River system.
