- Abstract:
-
Demarcating farmland redline is an important means for farmland protection, which can slow down farmland occupation in metropolis fringe areas where massive construction activities frequently take place during urbanization proceess. Xinbei District in Changzhou City which is located in metropolitan fringe area with rapid urbanization was selected as study area in this research. Based on the analysis of the present farmland status and its characteristics, the returning farmland and reclaim-suitable rural residential land were then selected according to suitability of adjacent land patch. A specific resistance coefficient was then assigned to each land use type, and accumulated minimum resistance for other land use type convertedto farmland was calculated using MCR model. Accumulated minimum resistance was classified using standard deviation classification method in order to find a farmland property threshold, which demonstrates the location and shape of farmland redline. The result shows that the demarcated farmland redline region in Xinbei District has an area of 299.84 km2, which occupies 66.25% of the whole study area and contains 92.50% of current farmland, shall help to protect most of the farmland. This research shows that MCR model could be used to demarcate farmland redline effectively. Adopting different protection standards within different regions, which split by redline, can provide an important reference for farmland protection.
