基于生态位理论对福建省土地利用结构的分析与预测

以福建省为例,用生态元的势与态分析预测了土地利用结构的变化,构建了土地利用类型的数量生态位和生态位扩充压缩度的数学模型,从而反映了各土地利用类型生态元的变化程度与趋势.同时,对各类用地的年度数量生态位进行了横向与纵向分析,得出了各类用地规模的变化趋势及其在土地生态系统中的地位功能,并从土地利用类型的生态位扩充压缩分析进...

Analysis and Prediction of Fujian Province Land Use Structure Based on Niche Theory

In this paper,Fujian Province was used as an example,the potential and state of ecological unit were introduced to analysis and forecast the changes of the land use structure,and the mathematical model of the niche expansion and compression degree of land-use types was constructed to elucidate the various types of ecological land-use changes in levels and trends.The analysis of annual horizontal and vertical niche to various land types were performed,and the change trends of the land use scale and its function in the whole land ecosystem were obtained,which were confirmed by the niche expansion or compression analysis results of land-use type.These data suggested that in the entire region,the amount of cultivated land and forest lands reduce more quickly than ever before;garden land and the construction lands will be greatly increased,the rate of infrastructure land increase will be faster.The point of view that the land use structure is unreasonable and it is necessary to establish the scientific development view and in a sustainable way was proposed.
