Analysis of the land use configuration based on the ecosystem service function-a case study of Fuzhou City
This paper is aimed to present a modified method for the evaluation of a rational and sustainable land utilization pattern in hoping to promote the harmonious relation between man and the landthe material basis for his survival.In this context,the paper takes the land use situation in Fuzhou City,Fujian,as a case study.In doing so,we have introduced the formula of Shannon entropy and a modified one by using the land ecosystem service value instead of the land area in the evaluation system.The results show that the Shannon entropy of land ecosystem service configuration has been decreasing gradually during the study periods.In regard to the spatial heterogeneity of the Shannon entropy at the county level of Fuzhou,it shows that the values of Shannon entropy decreases gradually from Changle Town,Fuqing Town,Liangjiang County,Pingtan County,Minhou County,the City districts,.Luoyuan County,Minqing County to Yongtai County in a sequential order.This indicates that the suburban areas of the city belong to the high level area of Shannon entropy,while the center and the exurban or the outer-skirts of the city belong to the mid-level area of Shannon entropy.It also shows that the Shannon entropy of each type of the land ecosystem service structure sequence from big to small in a progressive order:unused land,grass land,arable land,construction land,forest land,water land,and garden land,while the variation of the Shannon entropy of each type of land is not obvious over time.Furthermore,Pearson correlation coefficient has been introduced to inspect which types of land play more important functions in the Shannon entropy of land ecosystem service structure in this paper.As a result,it can be seen that the forest lands,the waters land,the green lawn land and construction land are the main land use types that tend to affect the structure of the information entropy of the land ecosystem services.
