    Analysis of Water Resources Carrying Capacity in the Greater Bay Area Based on Index Probability Distribution by CHEN Juan, WANG Sen

    Published 2023-01-01
    “…Foshan is slightly higher than grade III and located in grade IV.The water resources carrying capacity of Zhuhai is relatively better,while that of Foshan is relatively poor.Regarding the coordination degree of water resources environment and economic society,Foshan exhibits moderate imbalance,while other cities all have low coordination.In view of this,some suggestions are provided,including controlling the total amount of water use,rationally allocating water resources,optimizing and adjusting the industrial structure,improving water use efficiency,protecting the water environment,and strengthening water conservation.…”

    Spatial-Temporal Variation of Vegetation NDVI and Its Response to Climate in Guangdong-Hong Kong-Macao Greater Bay Area from 2012 to 2021 by FU Xiang, LIU Hao

    Published 2023-01-01
    “…Exploring the normalized difference vegetation index (NDVI) variation of vegetation and its response to climate change in the Guangdong-Hong Kong-Macao Greater Bay Area is of great significance for regional ecological environment restoration and vegetation improvement.According to MODIS NDVI data and meteorological data,Sen trend analysis,coefficient of variation (CV),and correlation analysis were adopted to analyze the spatio-temporal variation characteristics of vegetation and its response to climate change in the Greater Bay Area in recent 10 years.The results show that:①The NDVI of the vegetation in the Greater Bay Area generally shows a slow upward trend,with a rising slope of 0.003 3 /a,and the effect of continuous improvement of vegetation is great;②the NDVI stability of vegetation in the Greater Bay Area is relatively strong,with an average CV of 0.054 8.The areas with low and lower fluctuation changes of vegetation account for 89.94%,while those with high and higher fluctuation changes are mainly distributed in Foshan,Zhongshan,Dongguan,Shenzhen,Zhuhai,south of Guangzhou,and other regions with rapid economic development;③the correlation between NDVI of vegetation and average temperature in the Greater Bay Area is higher than that between NDVI of vegetation and precipitation.Temperature is the dominant factor affecting vegetation growth,and precipitation is mainly negatively correlated with the NDVI of vegetation.The research results can provide a theoretical basis for the ecological environment governance and green sustainable development of the Guangdong-Hong Kong-Macao Greater Bay Area.…”
