The outcome revealed that the comprehensive effectiveness and pure technical effectiveness associated with the green economy in the Yellow River Delta counties showed a fluctuating upward trend from 2000 to 2015. The scale effectiveness showed a rapid increase biological half-life then stayed steady in a ‘Γ’ type trend, while the escalation in extensive efficiency transformepulation urbanization rate had side effects on green economic performance. There was a clear ‘environmental Kuznets’ effect between green financial performance and financial development degree.Under the back ground of quick urbanization, the issue of disconnected habitat patches in economically developed areas is especially prominent, where biodiversity is seriously threa-tened. Consequently, the building of ecological system is an important measure in order to connect habitat patches and shield biological habitats. We extracted environmental source areas of Foshan City utilizing the connection list and morphological spatial pattern analysis (MSPA). Potential environmental corridors were identified according to InVEST model and minimal collective opposition (MCR). Incorporating the radiation channels obtained from hydrological evaluation to construct an ecological network in Foshan City. The ecological network had been optimized by adding DC661 manufacturer ecological resource areas, stepping stones, and identifying fracture points. Finally, the system pre and post optimization had been evalua-ted from the areas of both framework and function according to community analysis method and circuit theory. The results showed that environmental system in Foshan City was consists of 10 ecological resource places, 8 important corridors, 37 general corridors, and 11 radiation stations. After optimization, 7 brand-new ecological resource places, 17 preparation corridors, 13 stepping-stones, and 80 fracture things were added. After optimization, the ecological network closing, the range price index in addition to connection degree index were 0.59, 1.94, and 0.73, correspondingly. The most existing thickness increased from 1.39 to 9.66 after optimization, showing that the optimized ecological community structure was much more perfect and highly connective.Extreme weather/climate events more than doubled as a result of global heating. Predicated on everyday files from 16 meteorological stations in the Poyang Lake Basin (PLB) from 1959 to 2019, we comprehensively investigated the temporal-spatial and non-stationarity qualities of extreme precipitation from three measurements (power, regularity and length of time) making use of PreWhite-ning Mann-Kendall (PWMK), extreme-point symmetric mode decomposition strategy (ESMD) additionally the generalized additive designs for area, scale and shape (GAMLSS). The results showed that the strength and regularity of extreme precipitation increased significantly into the PLB, whilst the period of severe precipitation reduced from 1959 to 2019. The severe precipitation had popular features of high-intensity, high-frequency, and quick length of time in the PLB. There clearly was a definite difference between flood period and non-flood season for severe precipitation. Extreme precipitation was focused into the north and central PLB through the flooding season plus in the central PLB during the non-flood period. The increasing trend of severe precipitation quantity had been 2.10 mm·a-1 within the Xinjiang basin, which had the greatest increment on the PLB. Within the flooding season, the extreme precipitation had longer timeframe but weaker strength and smaller range, contrasting with all the condition through the non-flood season. The power and frequency of extreme precipitation showed stationarity attributes into the PLB. But, the length of extreme precipitation revealed non-stationarity characteristics. With all the constant boost of severe precipitation quantity, the possibility of relevant disasters would increase.Groundwater, among the crucial liquid resources, plays a crucial role in keeping sustainable personal and economic development. The environmental payment of groundwater is an excellent tool for ensuring reasonable exploitation and usage of groundwater sources. However, there was deficiencies in associated researches, particularly compensation budget. We proposed a built-in groundwater settlement standard design, which contains four elements base, stimulus and punishment, analysis and development, and possible threat. The concern degree of compensation had been believed by deciding on local environment and fiscal conditions comprehensively. The model had been put on a total of 11 places in Shanxi Province to calculate the groundwater ecolo-gical compensation standard. The outcomes showed that the beds base compensation accounted for the biggest proportion within the total compensation, utilizing the non-market worth contributing a lot more than 60%. Our results suggested that groundwater had a high Laparoscopic donor right hemihepatectomy regulated solution worth. From 2008 to 2017, the growth coefficient of every city had somewhat increased, recommending the enhanced local financial level and improved settlement ability.
