Change Characteristics and Bearing Capacity Analysis of Water Resources in the Pearl River Delta
Taking the Pearl River Delta as the research object,based on 13 sets of data such as surface water resources,groundwater re-sources and precipitation in 2010-2020,the spatial and temporal distribution characteristics of water resources in various cities in the Pearl River Delta were analyzed.By constructing a comprehensive assessment system on the transport capacity of water resources,the water resources carrying capacity of the Pearl River Delta was further studied.The results showed that the surface water resources and groundwater resources in the Pearl River Delta showed similar trends.The total water consumption in the Pearl River Delta showed a decreasing trend,with a continuous improvement in water efficiency.The spatial distribution of industrial water and agricultural water was quite different.The water resources carrying capacity in the central area of the Pearl River Delta is generally low.The water re-sources carrying capacity in the Pearl River Delta from 2010 to 2020 is generally declining,which requires the government to make o-verall planning,adopt measures according to local conditions,and comprehensively analyze various water resources indicators to achieve harmony between humans and water environment.
