【摘要】：地質(zhì)環(huán)境是人類賴以生存的自然環(huán)境的重要組成部分,地質(zhì)環(huán)境質(zhì)量限定著人類工程活動的強(qiáng)度,因此開展區(qū)域地質(zhì)環(huán)境條件評價(jià),對于制定區(qū)域土地利用和社會發(fā)展規(guī)劃,促進(jìn)地區(qū)的可持續(xù)發(fā)展具有重要的現(xiàn)實(shí)意義。隨著社會經(jīng)濟(jì)發(fā)展和生產(chǎn)力不斷提高,人類工程活動強(qiáng)度越發(fā)強(qiáng)烈,工業(yè)、農(nóng)業(yè)污染物的排放造成地下水質(zhì)量變差、污染日趨嚴(yán)重,誘發(fā)的地質(zhì)災(zāi)害給居民生命和財(cái)產(chǎn)帶來安全隱患。因此,從可持續(xù)發(fā)展和加強(qiáng)生態(tài)文明建設(shè)考慮評價(jià)地質(zhì)環(huán)境,意義重大。本文以吉林省延吉市朝陽川地區(qū)為研究區(qū),系統(tǒng)分析了該區(qū)的水文地質(zhì)條件和工程地質(zhì)條件,并分別按照地下水類型及富水性和工程地質(zhì)特征進(jìn)行了分區(qū);在上述工作的基礎(chǔ)上開展了地下水質(zhì)量評價(jià)、地下水污染評價(jià)、地質(zhì)災(zāi)害危險(xiǎn)性評價(jià)以及土壤污染、水土流失等評價(jià),綜合分析了主要環(huán)境地質(zhì)問題的危害性、危險(xiǎn)性;最后提出了地質(zhì)環(huán)境保護(hù)和防治的建議。通過本次地質(zhì)環(huán)境評價(jià),確定延吉市朝陽川地區(qū)孔隙潛水質(zhì)量較差、污染嚴(yán)重、可利用資源量小,孔隙裂隙水資源量分布不均,地下水環(huán)境受人類工程活動影響較大;人類工程活動誘發(fā)地質(zhì)災(zāi)害日趨嚴(yán)重,但因其規(guī)模有限,危險(xiǎn)性不大�？傮w而言,該地區(qū)地質(zhì)環(huán)境脆弱,開發(fā)利用的同時(shí)一定要加強(qiáng)保護(hù)。
[Abstract]:Geological environment is an important part of the natural environment on which human beings depend for survival. The quality of geological environment limits the intensity of human engineering activities. Therefore, the development of regional geological environment condition evaluation is of great importance to the formulation of regional land use and social development planning. It is of great practical significance to promote regional sustainable development. With the development of social economy and the continuous improvement of productivity, the intensity of human engineering activities is becoming more and more intense. The discharge of industrial and agricultural pollutants causes the quality of groundwater to deteriorate and the pollution to become more and more serious. The induced geological disasters bring safety risks to residents' lives and property. Therefore, it is of great significance to evaluate the geological environment from the view of sustainable development and strengthening the construction of ecological civilization. Taking Chaoyang Sichuan area of Yanji City, Jilin Province as the study area, the hydrogeological conditions and engineering geological conditions in this area are systematically analyzed, and the groundwater types, water-rich and engineering geological characteristics are divided respectively. On the basis of the above work, the evaluation of groundwater quality, groundwater pollution, geological hazard, soil pollution and soil erosion are carried out, and the harmfulness and danger of the main environmental geological problems are comprehensively analyzed. Finally, some suggestions for geological environment protection and prevention are put forward. Through this geological environment evaluation, it is concluded that the quality of pore phreatic water in Chaoyang Sichuan area of Yanji City is poor, the pollution is serious, the amount of available resources is small, the distribution of pore fissure water resources is uneven, and the groundwater environment is greatly affected by human engineering activities. Geological hazards induced by human engineering activities are becoming more and more serious, but they are not dangerous because of their limited scale. In general, the geological environment in this area is fragile, development and utilization must be strengthened at the same time.
