| 摘 要： | 选取宁夏中部干旱带盐池县、同心县、红寺堡区、海原县为研究区,以宁夏为参照区,运用相对资源承载力理论测算中部干旱带研究区各县、各乡镇的相对资源承载力。研究表明:以宁夏为标准,宁夏中南部地区和研究区的综合承载力都处于超载状态,而且研究区超载更严重;就各单项资源的承载力来看,耕地资源承载力经济资源承载力水资源承载力;就各县区来说,同心县和海原县均处于超载状态,海原县超载更严重,盐池和红寺堡区处于基本平衡状态;就各乡镇来说,处于富裕状态的乡镇面积占所有乡镇面积的50.05%,基本平衡的乡镇面积只占8.75%,处于不同程度的超载状态的乡镇面积占41.20%;超载的乡镇主要分布在区域北部边缘的防沙治沙区、东部边缘的水土流失治理区、西南边缘的山区林草保护生态区。

| 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. |
