| 摘 要： | 统计分析了京津冀地区土地资源、地下水、湿地、矿产、地热和地质景观等资源条件分布,结果显示,平原区土壤质量总体良好,良好及以上等级土壤分布面积约占平原区面积的80.89%,适宜种植绿色农产品的面积为96363 km~2,富硒耕(园)地面积为1894 km~2;地下水可开采资源总量为188亿m~3/a,但呈现空间分布不均的特征;衡水湖等五大湿地分布面积约为614 km~2,近30年来减少了35.57%;金属矿产和非金属矿产资源丰富,例如铁矿资源储量98.4亿t,铜矿资源量111.50万t,石油地质储量249635.02万t;地热资源丰富,开发利用地热资源可替代3.43亿t标准煤;地质遗迹资源丰富,约有300余处可纳入环首都国家公园规划建设。同时,分析了活动断裂与地震、地面沉降、地裂缝、崩滑流和地面塌陷、地下水污染和湿地退化等主要环境地质问题现状;在此基础上,针对城镇发展和重要基础设施建设、湿地保护与修复、地下水资源开发利用、优质耕地资源保护和地质遗迹资开发利用等方面提出了地学建议,为区域规划建设提供地质安全保障和资源保障。

| Abstract: | The statistics of such resources as land resources, groundwater, wetland, minerals, geothermal and geological relics show that the soil quality is very good and the area of good and above-good grade possesses about 81%, in which the area of green agricultural products is 96363 km2, the area of selenium-rich cultivated and garden lands is 1894 km2; and the total amount of groundwater exploitation is 188 billion m3/a, suggesting characteristics of uneven spatial distribution; the area of five biggest wetlands including Hengshui Lake is about 614 km2, which has been reduced by about 35.57% in the past 30 years; the metal mineral and non-metallic mineral resources are abundant:iron ore reserves have reached 9840 million tons, the amount of copper mineral resources is 111.50 million tons, and oil geological reserves are about 2496.35 million tons; geothermal resources are rich, and the development and utilization of geothermal resources can replace 343 million tons of standard coal; geological relics are abundant, and 300 sites can be included in the Central Capital National Park Planning. Meanwhile, based on an analysis of main environmental geological problems such as active faults and earthquakes, ground collapse and fissures, landslides, land subsidence, groundwater pollution and wetland degradation in the Beijing-Tianjin-Hebei region, the authors put forward some geoscience suggestions for the urban and important infrastructure planning, wetland protection and restoration, groundwater exploitation, highquality arable land resources protection and geological relics development with the purpose of providing geological and resource safeguard for regional planning and construction. |
