Abstract
With the changing behavior of land use by explosive population growth, the ecological environment is constantly disturbed and destroyed by humans, and the value of ecosystem services is obviously degraded. After the introduction of the national new-type urbanization plan, counties have become the key areas to promote new-type urbanization, and county land use is exceptionally active. Therefore, it is especially urgent to grasp the impact of county land use changes on ecosystem service values. Based on remote sensing satellite image interpretation to obtain county land use classification data, the changes of ecosystem service values in County between 1995 and 2015 were thoroughly explored. The research results show that the total value of ecosystem services has increased in most regions during the 20 years, among which, the service value of Shunchang County has increased most significantly. In terms of the service values of different land use types in each region, woodland is the main contributor to ecological services in different regions. From different time periods, Jian’ou City had the highest value of woodland ecosystem services in 1995 and 2015. In contrast, Songxi County had a lower value of services for each ecosystem type during 20 years.

Xie et al [11] established a Chinese ecosystem service unit area value equivalent factor table, based on the research results of Costanza et al and combined with the actual situation in China, which provides a reference for the calculation of the value of ecosystem services in China, and the equivalent factor table is widely used by Chinese scholars
Summary
Land use has an integrated function of ecology, production and living (referred to as "triple life") [1], which transforms land with natural properties into an artificial ecosystem with social properties. Humans live in ecosystems, receiving gifts from them every moment and releasing harmful substances to them, which in serious cases lead to disruption of ecosystems and eventually affect human survival and development [3]. Land use change will cause changes in the environment on which human beings depend, affecting the structure and function of the earth's biosphere, chemosphere and physical sphere, and cause imbalance in the material and energy flows of the ecosystem, resulting in a drastic reduction of biodiversity and global warming [4]. It is important to study the value of ecosystem services under land use change for the conservation of regional ecosystem service functions
