The balance of ecological and economic benefits of sea-buckthorn

Abstract

Sea-buckthorn, with high economic value, is one of the important tree species for windbreak, sand fixation and conservation of water and soil. Based on this, an equilibrium analysis method for ecological and economic benefits of sea-buckthorn was proposed. After analyzing the ecological function and economic value of sea-buckthorn, based on the system theory, the utilization benefit equilibrium model of sea-buckthorn was constructed from economy and ecology two dimensions. The equilibrium of sea-buckthorn utilization benefit in an evolutionary cycle was divided into low-level symbiosis, coordinated development, limit development and regeneration development four stages. In order to comprehensively reflect the overall situation of sea-buckthorn utilization benefits, an index system including two major systems of social economy and ecological environment was designed, and 12 indicators in the ecological function and economic value analysis results of sea-buckthorn were selected to judge the interaction balance between economic benefits and ecological benefits. Taking Liaoning Province as the research object, the comprehensive economic and ecological benefits of sea-buckthorn utilization between 2004 and 2017 shows that during this period, the growth rate of ecological benefits was slower than that of economic benefits and had fluctuations. From the evolution curve of the equilibrium of utilization benefits, the sea-buckthorn in Liaoning Province is in the coordinated development stage, but the coupling degree has been increasing in recent years, indicating that the utilization benefits of sea-buckthorn in Liaoning Province may enter the limit development stage. According to the research results, this method can effectively analyze the balance of ecological and economic benefits of sea-buckthorn, which is conducive to the maximum value of sea-buckthorn.
