Abstract:Using the center of gravity model and ArcGIS software, the spatio-temporal change trend of water transfer from agriculture to non-agriculture(WTAN) was discussed in Henan Province, and its driving factors were analyzed with the ridge regression model. The results show that the center of gravity of WTAN generally moves from southwest to northeast in Henan Province, presenting a phased change; the degree of WTAN shows an upward trend, with the values being higher in central and western Henan Province, and relatively lower in eastern, southern, and northern Henan Province; the degree of WTAN has increasing trends in Jiyuan and other seven cities, has stably trends in Sanmenxia and other six cities, and has decreasing trends in Nanyang and other two cities. There are significant differences in temporal effects of different driving factors, and the factors can be classified into four types that have driving effect, constraining effect, regulating effect, and insignificant effect, respectively, on WTAN in Henan Province. There are also significant differences in spatial effects of different driving factors, and the driving factors have different kinds of effects in different regions.
