Eco-environmental susceptibility in Shangyi County,Northern Hebei Province,China

In this paper,the eco-environmental susceptibility of Shangyi County,Northern HebeiProvince of China has been calculated by using the weighted-addition method based on expert’s giv-ing a mark to each influencing factor according to their knowledge on the influence of all the factorson eco-environmental susceptibility.The eco-environmental classification and distribution map werereached based on the above results,its difference is mainly result from the physical conditions andhuman activity,however the value of eco-environmental susceptibility is only a relative index whichcan not completely reflect the quality of eco-environment.This work provided a basis for control-ling the further development of desertification.
