    摘要:

    运用重心模型与ArcGIS10.2软件,探讨河南省水资源“农转非”时空变化趋势,采用岭回归模型对其驱动因素的效应进行分析。结果表明:河南省水资源“农转非”重心轨迹整体由西南向东北移动,且呈阶段性变化特征;河南省水资源“农转非”程度呈现上升趋势,其中豫中、豫西较高,豫东、豫南、豫北较低;济源等8市“农转非”程度均有所提升,三门峡等7市保持稳定,南阳等3市则有所下降;河南省水资源“农转非”驱动因素的时间效应存在差异,依据驱动因素的正负效应以及变化情况可划分为4种类型,分别对河南省水资源“农转非”具有驱动、约束、调节和不明显的作用;河南省水资源“农转非”驱动因素的空间效应存在差异,不同区域驱动因素作用的差异显著。

    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.
