- Abstract:
- In order to study the coupling relationship between ecosystem services and farmers' livelihood, based on the land use data of the Three Gorges Reservoir Area from 1995 to 2015, combination of the situation of the reservoir area, the equivalent factor table of different ecosystems in China was revised to evaluate the different ecological service values of the reservoir area; the evaluation system of different livelihood capital of farmers was introduced to construct the coupling degree of the reservoir area, the coupling coordination degree model was used to analyze the coupling relationship and spatial distribution between the ecosystem services of the Three Gorges Reservoir Area and the livelihood of farmers. The calculation of the contribution rate of each ecosystem service to the livelihood of farmers was discussed, and the factors affecting the livelihood of ecosystem services by farmers were discussed. The results showed that:(1)the highest proportion of ecosystem services and farmers' livelihoods in the Three Gorges Reservoir Area was 65.38%, except for the Yuzhong District and Dadukou District in the tail area of the reservoir area, and the remaining districts and counties were moderately coupled; all districts and counties were gradually approaching from the recession development category to the impending recession, and the counties and counties on the verge of development were reluctant to coordinate development and coordinate the development of districts and counties;(2)the contribution rate of different types of ecosystem services to farmers' livelihoods was different; the agricultural income of rural households in the reservoir area was up to 55.31%;(3)the correlation between the ecosystem services of the Three Gorges Reservoir Area and the livelihood capital of different farmers was extremely strong; the human capital was most coupled to the ecosystem services; the coupling degree of the farmer's livelihood and support services was the highest, and the overall coordinated development level of the reservoir area was improving year by year. Ecosystem services in the Three Gorges Reservoir Area have the large contribution rate to farmers' livelihoods. Ecosystem services and farmers' livelihoods are highly correlated and the coupling relationship is obvious.
