Abstract. This paper reports on processes occurring within the human environment: shocks occurring in the environment; the increase in greenhouse gases from industry; the increase in greenhouse gases from agriculture; the change in global temperature; the reduction of freshwater resources; the change in area of forested land. The article also examines the impact of three groups of factors on the dynamics of environmental shocks. These factors are the history of the process, the impact of various dynamic factors of human life and the degree of influence of the processes occurring in the environment. The autoregressive distributed lags model (ADL model) is chosen as the theoretical framework for the analysis of the correlation between the environmental shocks and the influencing factors, and empirical testing of the model is performed. The exogenous variables characterising the factors of human life were analysed using the following indices: global GDP per capita; economically active global population; global merchandise exports (FOB); rail transport freight turnover (mln tons km -1 ); the mining of coal and lignite, extraction of peat, (mln USD). The forecast of the development of environmental shocks in 2017-2018 was performed. The analysis of the model showed that the dynamics of the environmental shocks had a constant trend.

“…Therefore, human activities must be clarified to study the impacts of human disturbances on water conservation services. In particular, land-use types are subject to intense human disturbances [55,56], which represent important causes of changes in regional water conser-vation. Population density and GDP reflect the level of urban socioeconomic development, which is a potential factor in water conservation changes [10,57].…”

Water conservation services are key indicators of ecological services. Against the backdrop of frequent extreme weather events and water scarcity caused by global climate change and intensified human activities, assessing these services and their drivers are crucial tasks for regional ecological security and sustainable development. Jiangxi Province is one of the first national ecological civilization pilot zones in China, representing an important ecological barrier in southern China. Exploring the characteristics of spatial and temporal changes in water conservation and their driving factors can facilitate the rational development and utilization of regional water resources and the construction of ecological civilizations. Therefore, based on long time series data, the InVEST model was used to explore the spatiotemporal evolution characteristics of water conservation services, and to elucidate the trend of their change through the Theil–Sen median trend analysis and the Mann–Kendall test; then, the geographic detector and geographically weighted regression model were used to further analyze the drivers of spatial variability of water conservation services. The results showed the following: (1) The average depth of water conservation was 103.18 mm, showing a spatial pattern of “low in the middle, high in the surroundings, high in the north and low in the south”. (2) Slight improvements were primarily observed (77.49%), with only 1.60% of the area showing significant improvements. (3) Land use was the main driver of the spatial differentiation, and the interaction between precipitation and forestland had a significantly greater effect on spatial heterogeneity than any single factor. (4) Obvious spatial heterogeneity occurred in the driving factor impacts, with natural factors (precipitation, evapotranspiration, forestland, and grassland) having a positive impact on water conservation services, and land-use factors (construction land and cropland) and socioeconomic factors (population density and land area) having a negative effect. This study provides a reference for water-conservation-based ecosystem construction and policy formulation in Jiangxi Province.

“…But this method has a significant disadvantage: it characterizes a specific geographic location (according to the limiting environmental factors). The reason for the disadvantage of this method is the assumption of using different units of measurement in the same equation [6,7,8,9].…”
