基于生态位适宜度模型的土地利用功能分区

土地利用功能分区是土地利用总体规划中的重要内容。该研究以生态位理论为基础，从生态角度进行土地利用功能分区定量研究。该研究提出了土地利用生态位的概念，并从土地利用需求生态位和现实生态位的耦合关系，构建土地利用生态位适宜度模型，建立土地利用生态位适宜度评价因子体系，并以土地利用生态位适宜度评价结果为表征量，借助GIS技术对土地利用功能进行分区。通过对山东省济南市的案例研究，运用该技术方法进行的土地利用功能分区，结果更加优化和合理，验证了该模型的实用性。该研究从生态适宜角度为土地利用分区的定量化研究提供了新的技术方法。

Land-use functional regionalization based on niche-fitness model

Land-use regionalization is one of important contents of general land-use planning. Land-use functional regionalization was studied quantitatively based on niche theory in the paper. Firstly, the concept of land-use niche was proposed, and then land-use niche-fitness model was built based on the coupling relationship between requirement niche and realistic niche. Secondly, indices of land-use niche-fitness evaluation were constructed. Finally, taking the result of land-use niche-fitness evaluation as a criterion, land-use was regionalized based on GIS. Taking Jinan City as a study area, the results showed that the regionalization project was optimal and reasonable, andthe practicality of the model was verified. This work can provide a new technique for the similar research of land-use regionalization from a view of niche-fitness.
