基于生态健康距离模型的大连城市居住用地安全研究

本文借助遥感和地理信息系统技术,运用生态学中的健康距离模型,对大连城市居住用地安全的差异及其影响因素进行实证研究。研究结果表明:大连城市居住用地安全空间差异性明显,普兰店、瓦房店、甘井子和庄河城市居住用地安全良好,沙河口、旅顺口和金州属于临界安全区,西岗、中山和长海属于敏感区。城市居住用地安全的重要影响因素包括与地震断裂带的距离、与地质灾害易发区的距离、与泄洪区的距离、与海岸带的距离以及其周边土地生态敏感度、水土流失程度等。

Study on Dalian Urban Residential Land Security Based on HD model

The paper analyzes Dalian Urban Residential Land Security differences and its main influencing factors, by remote sensing and geographic information system technology, using the Healthy distance model of the ecology. It shows that urban residential land security has obvious difference： Pulandian, Wafangdian, Zhuanghe ,Ganjingzi are the good zone, shahekou, Lvshunkou and Jinzhou are the criticality zone, Xigang,Zhong shan and Chang hai are sensitive zone; and that its main influencing factors contain Urban residential land security and seismic fault distance, and geological disaster-prone areas of the distance and the distance flood zone, and the distance between the coastal zone and its surrounding land ecological sensitivity, and the degree of soil erosion.
