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.

The reason for ecological fragility in Hotan river basin;

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.

This paper, from four aspects of population capacity, growing amount of communities and their biomass, eco-environmental sensitivity, and capacity resisting natural disasters, expounds the basic features of eco-environmental fragilities in Guizhou Karst mountain region and analyzes the causes and mechanism of eco-environmental fragility and suggests corresp.

This paper, taking 42 counties (or cities) in the Wujiang Basin as examples, deals with the main principles of rcgionalization of the eco-environmental fragility in karst area, discusses and quantifies the index of the fragility regionalization.
