Study on the evaluation of ecological frangibility of the wetlands in the Bosten Lake Region;

In the paper,in order to make the right ecological frangibility assessment for Linxiang,ecological assessment index system was first constructed.

Nature and economy system fluctuations, improper utilization of natural resources and ecological frangibility in Jiang-huai Water-shed have close relations in space distribution and cause of formation.

The assessment of ecological vulnerability is not only the important precondition of sustainable spatial planning,but also one of the important problems in the field of resources and environmental research.

This paper chose the 20 indexes and 2500 datas of 25 sample years which could measure ecological vulnerability at the upper reaches of Minjiang River and construct the index system of eco-environment vulnerability at the upper reaches of Minjiang River by adopting the methodology of regressive measure.
