【摘要】 应用计算机图像增强处理技术对江山市城区陆地卫星遥感图像数据和航空相片进行多种增强处理,为识别与岩溶塌陷有关的各种地质信息提供了有效的技术手段。利用各种增强处理的遥感图像,并结合实际调查资料,对岩溶塌陷的地质条件、时空分布规律进行了综合判读。通过判读基本查明了岩溶塌陷的地质条件和时空分布规律,并对岩溶塌陷的成因类型进行了分析,提出了相应的防治措施。对江山市城区工程和经济建设具有重要的现实意义。更多还原

【Abstract】 With the technology of the computer image enhancement processing, the Jianshan remote-sensing data of landsat and the air-photo is processed, some sufficient technological method for discerning all kind of the geological information of karst-subside is provided. Using all kind of enhancement processing image and connecting the practice, then interpretes the geological condition and the space-time law. And the geological condition and space-time spread law of the karst subside is found out, aralyzing the form type, and the protect method is quested. It is important for the project and economic construct in Jiangshan urban area.更多还原
