摘要:

分析探讨高原湖泊湿地的环境评价中,如何应用一套由植被为主指示要素构成的环评指标,并以云南石林长湖湖泊湿地为实例。按植被及其植物区系组成、动物区系和生境方面所表现特征的现况,共设置以植被特征为主的10个评定指示要素。使用此类指标评价的前提是:所评的各个高原湖泊湿地,均在上述10个所规定的指示要素方面,已取得调查研究的定量和定性数据资料。所以本方案的使用,反而促成各高原湖泊湿地在以植被特征为主各评价要素的进一步考察和研究,以作为参评的依据。

Abstract:

Using wetland of Changhu Lake as an example,this paper tried to establish assessment indices of lake wetlands,and they were based mainly on vegetation indicators. The established indices would been applied in assessing environmental conditions of plateau lake wetlands. 10 groups of indicators representing characteristics of vegetation,flora,fauna and habitats were carried out for assessment process. Applicability of the proposed indices was determined on the availability of qualitative and quantitative data related to indicators,which was the premise when assessing. Meanwhile,it was important to note that the usage of the indices would promote collecting the unknown data on vegetation,flora,fauna and habitats of each plateau lake wetland,which would help assessing it's environmental condition synthetically in the future.
