贵州省生态系统对酸沉降的相对敏感性

根据贵州的情况选用土壤、植被与土地利用类型、水分盈亏量3个生态因子,采用定量的方法对贵州省生态系统对酸沉降的相对敏感性进行研究,结果表明轻度敏感区面积最广占全省的61.28％,其次为较不敏感区和中度敏感区,分别占18.86％和18.04％,不敏感性区域占全省总面积的1.15％,敏感区所占面积比例最小为0.67％。并根据实际情况提出了防治对策。

The sensitivity of ecosystem to acidic deposition in Guizhou

Three ecological factors ase selected, namely, soil type, vegetation and landuse type, and water profit and loss. Based on Guizhou situation, this paper has adopted quantitative analysis method to study the relative sensitivity of Guizhou ecosystem to acid deposition. The widest area is light sensitivity area which is about 61. 28% of the whole province. The relative non - sensitivity area and the moderate sensitivity area are 18. 86% and 18.04% respectively. The non - sensitivity area is about 1. 15% of the whole province. The smallest area is sensitivity area which is only 0. 67%. This paper also puts forward the way of how to prevent and manage according to actual situations.
