摘 要: | In this paper,the eco-environmental susceptibility of Shangyi County,Northern Hebei Province of China has been calculated by using the weighted-addition method based on expert's giving a mark to each influencing factor according to their knowledge on the influence of all the factors on eco-environmental susceptibility.The eco-environmental classification and distribution map were reached based on the above results,its difference is mainly result from the physical conditions and human activity,however the value of eco-environmental susceptibility is only a relative index which can not completely reflect the quality of eco-environment.This work provided a basis for controlling the further development of desertification.
