摘要:

基于美国陆地卫星ETM遥感数据等,构建了基于Skyline数字地球模型的长江流域三维场景可视化遥感演示系统,以ERDAS、ARCGIS、MAPGIS等软件为平台,全面完成长江流域地貌遥感解译,系统提取了多时相城市扩展遥感信息,以环境科学与可持续发展理论为指导,结合流域内水患灾害问题及社会经济可持续发展的长远目标,提出长江流域地貌约束条件下的国土开发与水患治理新理念与对策。结果表明:采用成因-成因形态-物质形态相结合的地貌遥感三级综合分类法,宏观掌握了长江流域地貌物质成因类型、结构及展布特征等,共计圈定长江流域基本地貌单元16 770个,地貌以山地、丘陵、高原类型占主导,平原面积总计36万km2,占比较小,地貌单元分块、成带、定向排列特征突出,物质构成复杂多变,是国土开发与保护的基础条件与重要约束因子;通过遥感立体演示系统新发现了相隔湖北嘉鱼市斧头湖与阳新县网湖的山丘地存在一条东西向展布的长36 km的槽谷地貌,分析认为可顺应此谷,构建联通斧头湖与网湖亦即贯通长江的大分洪道,全长仅139 km,现绕行武汉的291 km长江弯道能因之缩短152 km,并提出“依丘穿岗、多刻槽、慎筑墙,避让不移民、土地占补就近平衡,国土整治、生态农业相依托,灌溉、航运、旅游综合考量”的长江大分洪道构建思想,认为通过构建长江大分洪道与实施小微型蓄水工程,可实现长江流域水患根治的终极目标;长江流域适宜水、旱农业耕作的红层与岩溶盆地及花岗岩丘岗地貌区风化残积层分布空间广阔,农耕地开发潜力极大,未来长江经济带城市建设不存在土地瓶颈制约问题

Abstract:

Based on American landsat ETM remote sensing data and so on, this paper constructed remote sensing demonstration system of 3D visualization based on Skyline digital earth model. Based on ERDAS, ARCGIS, MAPGIS and so on software platforms, it extracted remote sensing information of landscape and city expansion in the Yangtze River basin, regarding the environmental science and the theory of sustainable development as guidance, and combining with the basin flood disaster and the longterm goal of social economic sustainable development, this paper proposed the new ideas and countermeasures of land development and flood control under the condition of geomorphologic constraint in the Yangtze River basin. The results show that adopting the remote sensing three level classification of causecause formationphysical formation, and mastered the main landform types, structure and distribution characteristics of the Yangtze River basin; The basic landform units were fenced and the total number was 16 770; The landform was dominated by the mountainous region, hills and plateau types, in which the area of plain accounting a small share about 3.6×105km2; The geomorphic units of block, zonality and directional arrange with outstanding character, its material composition was complex and variable, so it was the important constraint factor of land development and protection; This paper found that there was a 36km long valley terrain latitudinally between Futou Lake of Jiayu city and Wang Lake of Yangxin County in Hubei through the remote sensing stereo system; So, we would accommodate this valley, constructing the large floodway between Futou Lake and Wang Lake through the Yangtze River; Its full length would be 139 km, and it would be 152 km shorter than the 291 km around Wuhan Yangtze River bend at present; So, this paper put forward a proposal which was along the hills and crossing over the down land, carving much more slots, building wall cautiously, keeping away the floodway and no migration, making a requisition of land and compensation in equilibrium and settling down in the neighborhood, land regulation and ecological agriculture depending on each other, considering the irrigation, shipping and tourism synthetically; Through the construction of the Yangtze River floodway and implementation of small and miniature store water project, it could realize the ultimate goal of flood radical solution, and its social, economic and ecological significance would be inestimable; The red layer which is suitable for water and dry farming , the karst basin and granite hilly landform with the weathered eluvium distributed widely, and agricultural development potential was great, so the land bottleneck problem of city construction in the Yangtze River economic belt would not exist in the future
