摘要
应用ArcGIS的空间分析方法和可达性分析模型,从现状条件、控湖条件和高速公路规划实施后3种情况分别对鄱阳湖生态经济区交通可达性进行了定量评价,揭示了不同条件下经济区内可达性值变化情况.结果表明:鄱阳湖水面对经济区可达性的影响是显著的,控湖对鄱阳湖生态经济区的可达性改善不明显,南昌—德兴高速规划实施后对经济区可达性改善效果显著.
Thanks to the help of the spatial analysis methods of ArcGIS and the model of accessibility analysis, the transport accessibility in Poyang Lake Eco-economic Region is evaluated by three cases, such as status conditions, lake-controlled conditions and after the implementation of highway planning. The values of accessibility are revealed under differ- ent conditions and the corresponding regional policies are put forward. The results show that the water of Poyang Lake has been influencing the accessibility of the economic zone significantly, the accessibility of the economic zone has no obvious improvement with lake-controlled conditions, the highway of Nanchang-Dexing which is in plan will improve the effect of accessibility significantly.
