The well-facilitied farmland construction is important initiative to strengthen farmland protection and ensure food security. Along with growing prominence of contradiction between land and population and farmland protection, it is imminent to research well-facilitied farmland construction. The construction project area location is not scientific, and research on the construction project area location of well-facilitied farmland can resolve it. It can provide support of theory for well-facilitied farmland construction and information management. Taking Xinzheng City in Henan Province as an example, the suitability and spatial stability of the well-facilitied farmland construction were researched based on evaluation model of suitability and spatial stability of the well-facilitied farmland construction to improve scientificity of construction project area location of well-facilitied farmland. Then optimum model of construction project area was established based on coupling coordination degree to confirm difficulty of well-facilitied farmland construction. The agglomeration of difficulty level was explicitly by Hot-Spot analysis, and the construction project area was selected. The result showed that basically possesses of construction difficulty was the largest, the area of farmland was 33731.84hm2, the proportion was 62.27%. According to the difficulty of farmland construction, the well-facilitied farmland construction project area was selected, which contained five construction project areas. The Xincun Town, Chengguan Township, Guanyinsi Town, Lihe Town, Baqian Township and Xindian Town were involved. The well-facilitied farmland can be built with area of 3455.87hm2. It provided scientific basis for project location selection of well-facilitied farmland construction.
