Abstract:: Changes in land use structure are the focus of attention to implement integrated land use plans. Based on digital land use maps of 2005 and 2010, this research showed changes in land use structure in He’nan Province between 2005 and 2010, exerting GIS techniques and mathematical methods. At the whole province scale, the significant quantitative changes in land use structure were that the areas of construction land and unused land increased greatly (increase rates were 6.71% and 16.97%, respectively), and that the areas of cultivated land and water body decreased markedly (decrease rates were 1.26% and 0.98%, respectively); the significant spatial changes were the location swap between cultivated land and forestland, water body and construction land, and the conversion of water body to unused land. At the integrated land use zone scale, in four land use zones the area of construction land increased by 3.70% to 16.71%, while the area of cultivated land decreased by 0.48% to 2.15%. In addition, the increase of unused land and forest land, and the decrease of water body in Zhongyuan Urban Community zone, the loss of forest land and water body in Yubei Zone, the gain of water body in Yuxinan Zone,and the increase of grassland in Huanghuai Four Municipalities Zone were the more significant changes. With respect to spatial changes, the location swap between cultivated land and construction land was extensive and significant in four zones. In addition, the location swap between cultivated land and forestland, and water body in Zhongyuan Urban Community Zone, the conversion of forest land and water body to cultivated land in Yubei Zone, the conversion of cultivated land to water body in Yuxinan Zone, and the location swap between cultivated land and water body, and the conversion of cultivated land to grassland in Huanghuai Four Municipalities Zone were the more significant changes. These findings provide valuable information for the implementation of He’nan integrated land use plan (2006—2020).
