摘要
基于生态承载力理论,计算和分析了秦岭北麓的生态承载力情况,结果表明:秦岭北麓的生态弹性指数大于50,说明其生态系统的弹性能力属于中等水平,即具有中等的自我维持与自我调节能力;水资源和土地资源均具有比较高的承载能力,但土地资源的承载能力更具优势,承载指数大于70,水资源的承载指数则小于70;在资源的承载压力度分析中,土地资源的承载压力比较小,而水资源的承载压力非常大,已超负荷,在11个区县中,最低的承载压力度为2.84,最高的已达到33.89的强压水平,水资源已成为社会经济发展的“瓶颈”。
Based on the ecological canting capacity theory, calculated and analysed the situation of the ecological carrying capacity on the Northern slope of Qinling Mountains.The result shows：the ecological elastic index on the northern slope of Qinling Mountains is above 50, which proves that the ecosystem elastic capacity is a medium level,that is , the ecosystem itself has medium keeping and regulating ability; Two kinds of main resources both have higher carrying capacity,but the land resource caning capacity has more advantage, its canting index is above 70 while the water resource carrying index is under 70.Among the analysis of the resource canTing-pressing index,the land resource has a little pressure,but the water resource carrying-pressing index is very great,it has already overloaded.In 11 counties,the lowest cantingpressing index is 2.84,the highest one is already up to 33.89,the water resource has already become the restriction factor of social progress and economic development.
