【摘要】 以重庆梁滩河下游流域为例分析研究水体中Hg、Cr、As、Zn、Pb5种重金属元素的空间分布规律,并建立了适合研究区小流域地表水生态风险评价的等级标准,得出研究区水体中Hg(3330.72)、Cr的生态风险大于As、Pb,而As、Pb的生态风险大于Zn。最后估算了重庆市城乡接合部由于污染造成的场内经济损失约为107848×104元·年-1,占农村工业总产值的4.29%。加上生态潜在损失与农业生产损失可达3773723.2×104～66093601×104元·年-1,平均为重庆农村工业总利润的34倍,占到农村工业总产值的77.5%。更多还原

【Abstract】 Example on the catchment area of LiangTan River in Chongqing , the paper analyze the Ecological Polluted Risk of Hg、Cr、 As、Zn、Pb, and set up a ranking standard compatibly. And think that the Ecological Risk of Hg(3 330.72)、Cr is higher, and As、 Pb is biggish to Zn. Then, by using James model and analyzing one case, indicated that: just calculate the expense of in-board, the expense of economy is about 107 848×104 yuan per year, and it was 4.29% of total production value of rural industry. Plus the expense of environmental father, it up to 3 773 723.2×104～66 093 601×104 yuan per year. This date is 34 times as gross profit of country industry, and up to 77.5% of total production value of rural industry. So, it is necessary to establish rational policy, and replace high cost, high pollution model to low cost, low pollution model.更多还原
