摘要
地质灾害可造成不同程度的土地损毁及水土流失。笔者选取地质灾害频发区(四川绵竹)在汶川地震期间及震后恢复有代表性的时间段,进行土地利用响应机制研究。结合GIS、RS技术与地理统计方法探究地质灾害的分布规律;从宏观和微观2个尺度探索地质灾害引发的土地利用结构、幅度、速度、程度、地震烈度、水土流失及土地敏感性的时空响应机制;总结出一套地质灾害对土地利用响应的研究方法;并依据分析结果对灾区土地合理利用及灾后恢复提出措施。
Geological disasters cause land damage and water and soil loss.This paper carried out the land use response mechanism of the earthquake in disaster-prone area of Mianzhu city in Wenchuan earthquake and its recovery periods.Based on GIS,RS technology and geographical statistics method,the distribution law of geological hazards were analyzed.The response mechanism in the structure,the amplitude,the speed and the degree of land use,the seismic intensity,the water and soil loss and the land sensitivity caused by geological hazards was explored from both macro and micro dimensions.The authors summarized some research methods of land use response to geological disasters and also put forward some measures to rationally utilize land in the disaster area.
