- Abstract
Ecological assets are the value of ecosystem services, which directly or indirectly provide products and services to human beings through the structure, process and function of the ecosystem. It is of great practical significance to study the service value of ecological assets and its relationship with green development. Based on the land use data of Shennongjia forest region from 2009 to 2018, combined with the ecological service value equivalent table per unit area of terrestrial ecosystem, it analyzed the total ecological asset value of Shennongjia forest region from 2009 to 2018. The results are as follows. (1) From 2009 to 2018, the service value of ecological assets in Shennongjia forest region showed a downward trend, and the service value of ecological assets decreased from 34809.87 million yuan in 2009 to 34650.79 million yuan in 2018. In ten years, the ecological asset service value of Shennongjia forest region decreased by 159.08 million yuan, with the change rate of -0.46 %. Among them, the service value of ecological assets of forest land accounted for the largest proportion, accounting for 97.66% of the value. (2) From 2009 to 2018, the service value of single ecological asset in Shennongjia declined, among which the decrease of hydrological regulation service value was the largest, with a decrease of 21.61%; and the decrease of food production service value was the smallest, which was 1.69%. The non-use value of ecological assets was 2.7 times of the use value, accounting for 73.10%. (3) By using BP neural network model, it is predicted that the proportion of green economy in Shennongjia forest region will reach 75.17% in 2023, and the service value of ecological assets is significantly correlated with green development, and the correlation coefficient is 0.9287 (P < 0.05), indicating that green ecological assets are the foundation and foundation of green development. The protection of ecological assets in Shennongjia is conducive to the sustainable development of the region.
