中文摘要：

为了区域的土地可持续利用和人地关系的和谐,以福州市为例,利用1993、2004和2009年土地利用变更调查数据,在Shannon信息熵公式的基础上,提出以土地生态系统服务功能价值指标代替面积指标计算土地利用结构信息熵,对土地利用功能结构进行分析。结果表明：福州市在1993、2004和2009年土地生态服务功能结构信息熵逐渐降低;各县市（区）的土地生态服务功能结构信息熵表现出明显的空间异质性特征,其中近郊区属于信息熵高值区,而中心区和远郊区属于信息熵中值区;各土地利用类型的生态服务空间结构信息熵也有较明显的差异,且随时间变化规律不明显;Pearson相关分析表明,林地、水域、耕地和建设用地是影响福州市土地生态系统服务功能结构信息熵的主要因素。研究表明,提出的土地生态服务功能结构信息熵不但能反映土地利用结构特征,而且能够反映土地的生态服务功能特征。

英文摘要：

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 land—the 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.
