摘要：

生态安全隐患区域的空间检测和获取对城市生态安全保护起到重要的作用。论文利用智能计算模型和空间分析技术,对广州市城市生态用地空间冲突与生态安全隐患进行了多情景模拟和分析。研究表明：① 空间冲突区域主要分布在城市边缘区。在城市生态用地占广州市总面积的15%、30%和50%情景下,分别占空间冲突总面积的95.40%、86.28%和77.45%,白云、花都、天河和番禺是空间冲突发生的主要区域。与之相反,城市核心区冲突区域面积所占比例逐渐增加。在50%情景时,空间冲突区域面积急剧增加,广州市城市生态用地控制指标面临着巨大的空间冲突压力。② 城市生态安全隐患区域主要分布在城市边缘区,在50%情景时,城市边缘区的隐患区域面积占隐患区域总面积的74.13%,白云区和花都区是生态安全隐患区域分布最集中的区域。而位于城市核心区的隐患区域,面临着更大的生态安全压力。研究结果可为城市生态安全的监控和预警提供参考,为城市生态保护提供可借鉴的方法和分析工具。

Abstract:

The detection and obtainment of ecological security hidden danger area plays an important role in the protection of urban ecological security. In this paper, based on the intelligent model and spatial analysis method, scenario simulation and analysis of spatial conflict and ecological security hidden danger were made for urban ecological land use in Guangzhou. Three scenarios with different proportion of ecological land were simulated. The research shows that: 1) spatial conflict areas mainly distribute in the urban fringe. In 15%, 30% and 50% scenarios, the urban fringe areas take 95.40%, 86.28% and 77.45% of the total area of spatial conflict respectively. Baiyun, Huadu, Tianhe and Panyu districts of Guangzhou are the major area of spatial conflict. With the increase of the percentage of ecological land, the proportion of spatial conflict in urban core area increase gradually. In 50% scenario, the urban ecological land in Guangzhou will face huge pressure of spatial conflict. 2) Areas with urban ecological security hidden danger mainly distribute in urban fringe area. In 50% scenario, the hidden danger area of urban fringe takes 74.13% of the hidden danger areas. Baiyun and Huadu districts are the most concentrated area of ecological security hidden dangers. While the areas with hidden dangers in the urban core area face greater ecological security pressure. The research results can provide advices for urban ecological security monitoring and pre-warning, and provide referential methods and tools for urban ecological protection.
