摘要:
系统梳理了成渝城市群以往地质调查成果,分析了区内地质资源对绿色发展的支撑点。结果表明: 成渝城市群天然气探明地质储量占全国的60%,页岩气累计探明储量近万亿立方米,涪陵焦石坝等已规模化开发气田; 地热资源较丰富,地埋管热源开发潜力较大; 芒硝等优势非金属矿产资源储量、开发基础较好,具有进一步产业化发展的基础; 现有中型以上岩盐矿产39处,地下空间尚未开发利用,盐穴资源开发潜力较大; 现有153处饮用天然矿泉水水源地,多含锶等有益元素,建议开展优质矿泉水品牌建设; 地质遗迹特色鲜明,现有164处重要地质遗迹,建议打造恐龙化石群等具有区域特色的品牌; 耕地资源较丰富,覆盖50%以上的土地面积,总体养分丰富,局部富硒,已形成一定数量的农产品品牌,建议开展都江堰—绵阳等地标准化农田建设,培育富硒农产品。建议进一步开展成渝城市群空白区土地质量调查、区域与重点产业地质调查等工作,以期持续提高地质资源对成渝城市群绿色发展的支撑作用。
Abstract:
Previous geological survey achievements of Chengdu-Chongqing Urban Agglomeration were carded systematically and the support points of Geological resources on the green urban development were analyzed in this paper. The results show that the proven geological reserves of natural gas in the Chengdu-Chongqing Urban Agglomeration area account for 60% of the national reserves and the proven total reserves of shale gas approach nearly 1 trillion cubic meters, with large-scale development of gas field being realized in Jiaoshiba of Fuling district. The geothermal resources are abundant and the potential for the development of buried pipe heat resources are huge. The mirabilites and other competitive non-metallic mineral resources show great reserves and good conditions for development, which is good for further industrialized development. There are 39 middle and large-sized rock salt mines, with undevelopment underground space, which means huge potential for the development of salt cavern resources can be expected. 153 sources of natural drinking mineral water are distributed in this area and most of them contain Sr and other beneficial elements, thus the development of top-grade drinking mineral water is recommended. Geological relics in this area have bright features, with 164 important geological relics being identified, so the construction of regional brands featwing in dinosaur fossil groups is recommended. The farmland resources are abundant here, accounting for more than 50% of the total land area. The total nutrients are abundant in this area and some regional areas are rich in Se, with the development of some brands of agricultural products. Thus the construction of standard farmland is recommended in Dujiangyan-Mianyang area to develop Se-rich agricultural products. Further survey on the land quality in blank areas of the Chengdu-Chongqing Urban Agglomeration, and regional and key industries geological survey are recommended to constantly improve the effects of natural resources in supporting the green development of the Chengdu-Chongqing Urban Agglomeration.
