| Abstract: |
| Selected the Yanchi County, Tongxin County, Hongsibu Region and Haiyuan County (YTHH) in central arid zone of Ningxia for the research areas, taken Ningxia as the reference area, using the theory of relative resources bearing capacity, culculated the relative resources bearing capacity of each county and township in YTHH Areas. The research showed that: Taking Ningxia for the standard, the comprehensive bearing capacity of the Central Southern Ningxia and YTHH Areas were in overload status, and the overload was more serious in the YTHH Areas. On the bearing capacity for individual resources, has shown the cultivated land resources>economic resources>water resources. On each County and Region, the Tongxin and Haiyuan County were in overload status, Haiyuan County was more serious overload, Yanchi and Hongsibu Region were in basic balance status. On each township, the areas which were rich status accounted for 50.05% of whole townships areas, the areas which were basic balance only accounted for 8.75%, townships with 41.20% areas were in different degree of overload condition. The overload townships were mainly distributed in the northern edge of desertificated land, eastern edge of the soil and water erosion areas, southwest edge of the mountain grassland and forest ecological protection zone. |
