摘要
秦巴山区是我国人文、地理、气候等南北衔接过渡区 ,蕴藏着丰富的自然资源。也是环境地质灾害的多发区 ,是长江防护林体系重点整治区。本文采用遥感影像解译和野外调查的方法 ,以生态景观单元为评价客体 ,以地质 -生态环境质量为综合评价指标 ,建立多维评价信息空间 ,通过综合评价地质 -生态环境自然状态 ,对本区地质 -生态环境资源现状和危及生态环境的各项因素进行了划分与探讨 ,提出了可持续发展建议。
By means of remote-sensing imagery interpretation and survey in the field ,taking ecological landscape as evaluation object ,and regarding geo-ecoenvironment quality as comprehensive evaluating criteria ,the system of multidimensional evaluated information space has been established.By making comprehensive evaluation about the geo-ecoenvironment state,the present of geo-ecoenvironment resources factors ,which are danger to ecoenvironment, have been classified and studied,and then it is given the suggestion for sustainable development.
