Abstract:: Based on the ecological carrying capacity theory,the situation of the ecological carrying capacity on the north slope of QinlingMountains is calculated and analyzed.The result shows:the ecological elastic index on the north slope of Qinling Mountains is above 50,the ecosystem itself has medium keeping and regulating ability;both water resource and land resource have higher carrying-capacity,but the land resource carrying capacity has more advantage,its carrying index is above 70 while the water resource carrying index is under 70.Seen from the resource carrying-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 water carrying-pressing 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.
