Abstract The Three Gorges Reservoir area (TGRA) has complex geological conditions and a fragile ecological environment. The construction of the Three Gorges Project triggered a series of ecological and environmental issues and social disputes, which have attracted much attention in recent years. However, it is still unclear how the temporal and spatial characteristics of ecosystem service value (ESV) in the TGRA changed in each stage of the Three Gorges Project along with the implementation of some ecological restoration projects. Based on four periods of land use data from 2000 to 2018, the changes in land use were studied and the ecosystem service values (ESVs) were estimated. Then, we analysed the spatial distribution and dynamic changes in ecosystem services. The results showed that from 2000 to 2018, grassland and construction land were the largest land use types showing area reductions and increases and the conversion of cropland to forestland, grassland and construction land represented the most important land type changes. In the past 18 years, due to the increase in forestland and water area, the ESVs increased by 2.7 billion yuan, with a growth rate of 3.46%. From the perspective of contribution rate, the conversion of cropland to forestland had the largest contribution rate to the increase in ESV. The ESV was higher in the northeast and lower in the southwest, and its changes have significant positive autocorrelation in spatial distribution. The hot spots of ESV change were mainly distributed in the main stream of the Yangtze River and the reservoir area. This research provides a reference for land resource allocation and experience for the ecological environment protection and sustainable development of the Yangtze River Basin.

Nps Pollution

Recently, increasing nutrient (i.e., nitrogen and phosphorus) concentrations have been observed in the surface water of many countries and the non-point source (NPS) pollution has become an important factor in the deterioration of water quality in the Three Gorges Reservoir Area (TGRA). The spatial and temporal analysis of NPS pollution loads in the TGRA of Hubei from 2005 to 2009 were estimated using export coefficient model in this paper. The results indicated the nutrient from rainfall was the dominant NPS of both TN and TP pollution. The spatial analysis of N and P loads from NPS in the TGRA of Hubei showed that the nutrient loads in BD County and YL District were higher than the other two counties in the study area. These findings demonstrate that the model could provide a simple and reliable approach to evaluate N and P loads to TGRA of Hubei and may be useful for planning and management of the local agricultural watersheds
