摘  要：
针对城市边缘地带建设用地快速增长与优质农用地大量减少的矛盾,以驻马店为例,在充分考虑农田的生态服务功能的基础上,构建了建设用地生态适宜性评价系统和耕地自然生产潜力评价系统组成的生态适宜城区扩展用地评价方法,评价了城市建设用地的生态适宜性和农地的自然宜耕性,基于保护优质耕地的目标,划分了适宜性发展空间分区,将城市发展空间划分为重点开发、优化开发、限制开发和禁止开发4个类型,结合宜居城市建设对不同分区内的耕地功能用地进行了分析,探讨了扩展用地时空配置的方法和途径。结果表明:驻马店市重点、优化、限制和禁止开发区面积分别占研究区总面积的37.05%、28.87%、17.75%、16.33%。该评价方法为城市边缘地带新增建设用地的时空配置提供了参考。

摘  要：
Aimed at the problem of construction land sprawling out into agricultural land in urban fringe, a ecologically feasible space for urban land expanding evaluation system was designed, which was composed of land construction feasibility and ecologically evaluation system and land capability evaluation system. In this system not only the sightseeing function and tourism of agriculture, but also agriculture's landscape and ecological function are considered. Taking the city of Zhumadian as an example, land construction feasibility and cultivated land suitability evaluated were built. Considering high quality cultivated land should be protected, four types of synthetically suitability sub areas were obtained. Accordingly, urban development space consisting of primary construction zones, preferential construction zone, restricted construction zone and forbidden construction zone. The ways of application of spatial and temporal allocation of new build-up land were explored. The results showed that the areas of these four categories of Zhumadian accounted for 37.05%,28.87%, 17.75% and 16.33%, respectively. This method provides information support for the new construction land allocation in urban fringe.
