Abstract:

Ecosystem services are the basis for human survival and development. Clarifying the relationship between supply and demand of ecosystem services and applying differentiated management and control can contribute to human well-being. This research aimed at characterizing the relationship between supply and demand of agroecosystem services and their spatial heterogeneity. It used ecosystem service matrix based on land use and cover change data to obtain ecosystem service capability in different spaces. Two indices—supply and demand matching degree and coordination degree—were formulated to evaluate the agroecosystem service status and sustainability of administrative village units in Quzhou County in 2015. Based on the characteristics of local spatial agglomeration, the agroecosystem management areas of Quzhou County were divided, and the management measures for the districts were put forward by using local spatial autocorrelation analysis. The results show that: (1) Supply and demand matching degree and coordination degree can realize the overall evaluation of natural resources in the region. (2) The spatial differences of the supply and demand matching degree and coordination degree of agroecosystem services in Quzhou County in 2015 were obvious. The matching degree of Quzhou County was 1.0647, which was at the general equilibrium level, indicating that the supply and demand of agroecosystem services was in an equilibrium state. The coordination degree of Quzhou County was 0.8977, which was in a state of good coordination, indicating that the sustainability of regional ecosystem services was high. (3) The 339 administrative village units in Quzhou County can be divided into four primary agroecological management areas and 12 secondary agroecological management subareas. Differential management measures are proposed for the ecological areas: Ecological conservation area shall be protected strictly and large-scale construction is prohibited. Ecological protection area shall be protected comprehensively to improve production efficiency. Ecological improvement area should implement comprehensive improvement measures in order to improve the ecosystem. Ecological reconstruction area should implement overall ecological rehabilitation and targeted ecological reconstruction. This study can provide some references for the fine management and differential protection of regional ecosystem services.
