摘要： 空间冲突是城市化过程中各种矛盾形成与激化的直接原因,是影响区域可持续发展的关键因素,合理测度快速城市化地区的空间冲突水平,对于优化区域发展模式、 避免区域生态风险具有重要意义。在利用遥感与GIS技术分析长株潭近年来空间格局变化的基础上,量化影响区域生态安全的空间外部压力值、 生态风险暴露值、 生态风险效应值3个因子,构建基于生态安全的空间冲突测度模型,对长株潭地区的空间冲突水平进行评估。研究表明:近年来长株潭地区的空间冲突作用强度总体呈现上升趋势,1993—2008年其冲突指数均值由0.264增长到0.323,且严重失控级别空间冲突的区域面积比例增幅最大,达1.07倍;不同空间类型的空间冲突强度不同,林地、 耕地的空间冲突水平相对较低,建设用地的空间冲突水平较高;城乡过渡地带是空间格局变化最为频繁、 空间冲突最为激烈的区域,其次是城市内部,农村地区的空间冲突强度远远低于城市。

Abstract: Spatial conflict, a direct cause for the formation and intensification of contradictions in the process of urbanization, is the key factor for regional sustainable development. It is essential to measure the level of spatial conflict for optimizing regional development model and avoiding the ecological risk. Based on analyzing the changes of Changsha-Zhuzhou-Xiangtan Urban Agglomeration’s spatial pattern from 1993 to 2008 by using remote sensing image processing software (ENVI) and GIS analysis software (ArcGIS), and quantifying the external pressure, ecological risk exposure and the value of ecological risk of space resources affecting ecological security of the region, this article builds a comprehensive conflict measure model based on ecological safety, and assesses the level of spatial conflict of Changsha-Zhuzhou-Xiangtan Urban Agglomeration which has experienced rapid urbanization. Research results can be obtained as following. Spatial conflict is an objective geographical phenomenon arising with the competition for spatial resources, which stems from the scarcity of space resources and the spillover of space functions. The level of spatial conflict can be characterized by three factors, which are external pressure, ecological risk exposure and the value of ecological risk of space resources affecting ecological security of the region. From the measurement results of Changsha-Zhuzhou-Xiangtan Urban Agglomeration’s spatial conflict, we can draw out that, with the increasingly frequent changes in spatial patterns of Changsha-Zhuzhou-Xiangtan region in recent years, the spatial conflict of Changsha-Zhuzhou-Xiangtan Urban Agglomeration presents a rising trend overall. From 1993 to 2008, the average value of spatial conflict index increased from 0.264 to 0.323. And the seriously uncontrollable spatial conflict increases the biggest in area ratio, up to 1.07 times. Different spatial landscape types have different ecological benefits. Therefore, there are some differences in intensity of the spatial conflict between the landscape types. The level of woodland and farmland landscape spatial conflict is lower, and the construction landscape conflict’s level is higher. Urban and rural transitional zone has the most frequent, intense spatial conflict of the region, followed by the inner cities, and the intensity of rural areas’ spatial conflict is far lower than in urban space.

Key words: spatial conflict, measurement of conflict, spatial ecological security, Changsha-Zhuzhou-Xiangtan Urban Agglomeration
