鲁西北平原土地资源结构区域分异及土地高效持续利用模式

The aim of this project is to study the association, function and spatial differentiation of land patterns (or land structure) in the northwestern part of Shandong Province. A method trying to use quantitative indices to describe land structure was established. The research works were completed following the original plan. The works done include: (1) using quantitative indices to describe land structure in the study area, (2) studies on the changes in land use, especially those in arable land, (3) using land productivity to indicate the functions of various types of land, (4) studies on land labor carrying capacity to reflect the relationship between land structure and land use, and (5) studies on the problems of present land use and suggestions for improvement. The productivity of land was estimated by investigation and theoretical calculation. Land labor carrying capacity is a concept proposed in this study to estimate the maximum labor amount that can be carried in a specific area of land. The calculation of land labor carrying capacity will help the estimation of surplus of labor in the area.

研究鲁西北平原土地资源结构的组合类型、功能及空间分异特点，并在此基础上提出鲁西北平原土地资源高效持续利用的分区和模式。在学科上探索土地资源结构的定量研究方法，用一系列指数描述土地结构中各组分之间的组合关系，从而建立分析土地结构功能、划分土地结构类型的方法，并把土地资源结构区域分异特点作为土地合理利用的基础。
