Temporal and spatial evolution of water resources carrying capacity in S City based on principal component analysis
Evaluation of water resource carrying capacity is the basis for rational allocation,utilization,and development of water resources.Based on the statistical data of S City from 2012 to 2021,the evaluation system of water resources carrying capacity was established by selecting 15 indexes including total population at the end of the year.The principal component analysis method was used to analyze the temporal and spatial evolution of the water resources carrying capacity in S City.The results showed that the main factors affecting the water resources carrying capacity in the study area include the level of social and economic development,population and agricultural development factors and the natural condition of water resources;from the perspective of time,the water resources carrying capacity of the study area showed a trend of fluctuant increase from 2012 to 2021;from the perspective of space,the water resources carrying capacity of the study area generally presents the highest spatial pattern in the east,followed by the middle and north.
