【摘要】：山、水、林、田、湖是一个相互联结、相互作用、相互演进的生命共同体。三峡库区就是一个山、水、林、田、湖等多要素构成的典型的生命共同体,各要素的动态变化影响整个生命共同体的协调发展及结构功能,并对长江中下游的生态安全与可持续发展有重要影响。本研究从《重庆统计年鉴》和《重庆水资源公报》收集基础统计数据;并将30米空间分辨率的TM影像结合监督分类和目视解译,获取土地利用分类数据;再通过DEM获得平均海拔、坡度等。根据山水田林湖生命共同体的概念内涵,主要在山体结构、水体流量、森林功能、农业生产、河湖环境、人类生活这六个方面,构建基于山-水-林-田-湖-人的指标体系模型。同时选取系统聚类分析作为研究方法,分别对2003年和2015年重庆三峡库区山水林田湖生命共同体的健康状况、格局进行诊断。最后将这两年重庆三峡库区山水林田湖生命共同体的健康状况进行对比分析。2015年的健康诊断结果表明:万州、涪陵、云阳、开县、巫山、忠县、奉节、丰都、武隆、石柱、长寿、渝北、巴南、江津、北碚属于健康区;沙坪坝、南岸、九龙坡、大渡口、江北属于不健康区;巫溪是轻度病态区。2003年的健康诊断结果表明:南岸、九龙坡、大渡口、江北、涪陵、忠县、长寿、渝北、巴南、江津、北碚属于亚健康区;巫溪是轻度病态区;万州、云阳、开县、巫山、奉节、丰都、武隆、石柱属于中度病态区。2003年至2015年的研究变化表现为:健康区城市由0个增加到15个;亚健康区城市由11个降低到0个;不健康区城市0个增加到5个;轻度病态区仍然是巫溪;中度病态区从8个减低到0个。总体上,重庆三峡库区山水林田湖生命共同体的健康状态有逐渐变好的趋势,这主要是因为田系统和人系统的健康状态变好。
[Abstract]:Mountain, water, forest, field, lake is a life community that interconnects, interacts and evolves mutually. The three Gorges Reservoir area is a typical life community composed of mountain, water, forest, field, lake and so on. The dynamic changes of each element affect the coordinated development and structural function of the whole life community. This study collected basic statistical data from Chongqing Statistical Yearbook and Chongqing Water Resources Bulletin. The TM images with spatial resolution of 30 meters are combined with supervised classification and visual interpretation to obtain land use classification data. According to the concept connotation of life community of Lake Tian Lin, it is mainly in mountain structure, water flow, forest function, agricultural production, river and lake environment. In these six aspects of human life, the index system model based on mountain-water-forest-field-lake-man is constructed. At the same time, the system cluster analysis is selected as the research method. On 2003 and 2015, respectively, the health status of the life community of mountain, water, forest and lake in the three Gorges Reservoir area of Chongqing was studied. Finally, the health status of the life community of mountain, water, forest and lake in the three Gorges Reservoir area of Chongqing during the past two years was compared and analyzed. The results of health diagnosis in 2015 showed that: Wanzhou, Fuling, Yunyang, Kaixian. Wushan, Zhongxian, Fengjie, Fengdu, Wulong, Shizhu, longevity, Yubei, Bannan, Jiang Jin, Beibei belong to the healthy district; Shapingba, south bank, Jiulongpo, Dadukou, Jiangbei belong to unhealthy area; In 2003, the health diagnosis results of Wuxi were as follows: South Bank, Jiulongpo, Dadukou, Jiangbei, Fuling, Zhongxian, Longshou, Yubei, Bannan, Jiang Jin, Beibei belong to sub-healthy area; Wuxi is a mild pathological area; Wanzhou, Yunyang, Kaixian, Wushan, Fengjie, Fengdu, Wulong and Shizhu belong to moderate morbid areas. The number of cities in sub-health areas decreased from 11 to 0; The number of cities in unhealthy areas increased from 0 to 5; The mild pathological area is still Wuxi; In general, the health status of the life community of the mountain, water, forest and lake in the three Gorges Reservoir area of Chongqing has gradually improved, which is mainly due to the improvement of the health status of the field system and the human system.
