Abstract: 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.
