【Abstract】 The partition of ecological environment according to disturbance degree can direct and regulate the disturbance intensity and pattern of human activities,favoring to rationally develop resources and to protect ecological environment.Taking Qianxi county,Hebei province,for example,we put forward the principles to select influencing factors,then graded,evaluated them and fixed on their weight by grey system analysis. After comprehensive judge, the ecological environment of Qianxi county was divided into medium degree disturbance area and light degree disturbance area,and further into medium one degree disturbance area,medium two degree disturbance area, medium three degree disturbance area,light one degree disturbance area,and light two degree disturbance area. Aiming at every disturbance area, we indicated the corresponding countermeasures to regulate the intensity and pattern of human activities.更多还原
