| 6. | To coordinate the western development of the country , in 2000 , the project of " underground water resources exploration and eco - environmental geological survey in karst rock mountainous areas southwestern china " laid by the china geological survey was started 摘要为配合西部大开发,中国地质调查局2000年下达“西南岩溶石山地区地下水资源勘查与生态环境地质调查”项目任务,开展了新一轮西南岩溶石山地区地下水资源勘查与生态环境地质调查工作。 |
| 7. | The high - intense exploitation of mineral resources have brought about a series of environmental problems over recent 20 years in china , such as the large - area failure and subsidence of ground , underground water resources having been dried up and serious air and water sources pollutions in mining districts 摘要我国矿产资源、近20年来的高强度开采带来了一系列的环境问题,造成了地面的大面积破坏和塌陷;导致矿区地下水资源、枯竭和矿区严重的大气、水源污染。 |
| 8. | In this thesis , beginning with a comment on tin surveying achievement and existed problems , the technical methods for underground water resources exploration and eco - environmental geological survey in the karst rock mountainous areas in southwestern china is discussed , providing for conference for the geologists in the field concerned 本文首先评述了当前调查工作取得的成果及存在的问题,提出并讨论了西南岩溶石山地区地下水资源勘查与生态环境地质调查工作的技术与方法。 |
| 9. | ( 3 ) by analysis the environmental bearing capacity of emphasis leakage catchment water area , the main factor of limiting the development of the study area is the exploitation of the underground water resource and the population , thus when further constructed , it should not broaden the population scale and should to save the water quantity . dajiangou and beikang are out of the bearing capacity . real estate construction must avoid the two fields ( 3 )分析研究区内重点渗漏区汇水范围区域的环境承载力,得出限制研究区发展的主导因素就是地下水资源开采量及人口规模,因此研究区进行建设时,不易再扩大人口规模,应尽量节约水资源用量,可引用外水,大涧沟、北康2个汇水区均超出环境承载力,在进行区域开发建设过程中,应尽可能的避开这2个汇水区。 |
| 10. | The agricultural production holds an important position in baoding area , winter wheat and summer corn are the main grain crops and cotton is the main cash crop . the water resources used in agriculture include rainwater resources used directly by crops and surface water resources or underground water resources which is used through irrigation . there have been lots of rainwater waste because of lacking in research on rainwater resources utilization and in perfect engineering technology in baoding area . to make full use of rainwater is important to alleivate the water resources crisis and improve the ecological environment , the main objectives can make more rainwater turn into soilwater that can be utilized by crops directly and decrease the crops requirments for the surface and ground water resources 用于农业生产的水资源包括直接利用的雨水资源和通过灌溉补充的地表水资源和地下水资源。目前,保定市对直接用于农业生产的雨水资源尚未进行深入细致的研究,而且雨水资源的利用工程技术措施尚不完备,这种情况造成了雨水资源的浪费。显然,充分利用雨水资源,即尽可能多的把天然降水转化为可被作物利用的土壤水,减少作物对现有水资源(地表水资源和地下水资源)的需求,对于缓解保定市水资源供需矛盾,改善水环境与生态环境有重要的现实意义。 |
