Research on ecological carrying capacity evaluation of Lanzhou city based on county and district scale
Ecological carrying capacity is the main means to characterize the health level of regional ecosystems,and its quantitative analysis results can provide effective data support for regional ecological environment management and high-quality development decisions.Taking Lanzhou city as the research object,using statistical yearbook data,agricultural census data compilation,and data from the work reports of various district and county governments in Lanzhou city,an ecological carrying capacity evaluation system was established,including human settlement environment,economic environment,and natural environment carrying capacity.Based on the standardization of various data,the entropy method was used to assign weights and calculate the current ecological carrying capacity of each district and county in Lanzhou city.The results show that the ecological carrying capacity of some districts and counties is at the"healthy"level,but the ecological carrying capacity of Honggu District and Yuzhong County is at the"sub-health"level,and the ecological carrying capacity of Anning District and New District is at the"unhealthy"and"sick"level respectively.
