【摘要】:水是人類社會(huì)生存和發(fā)展的基本物質(zhì)條件。在中國北方、干早、半干早地區(qū)的許多地區(qū)和城市,地下水已成為重要的甚至唯一的供水源。訥河市位于黑龍江省西北部,是黑龍江省主要的糧食生產(chǎn)基地。人們生活及工農(nóng)業(yè)發(fā)展對(duì)地下水資源的需求越來越大,對(duì)地下水的不合理開采,產(chǎn)生了局部地下水位下降;開展節(jié)水增糧項(xiàng)目,對(duì)訥河市地下水資源的合理開發(fā)利用提出了更高要求。因此,對(duì)訥河市地下水資源進(jìn)行評(píng)價(jià),提出訥河市地下水合理開發(fā)利用方案,旨在為該地區(qū)地下水開發(fā)利用提供科學(xué)依據(jù)。本文以訥河市節(jié)水增糧行動(dòng)為依托,通過收集已有資料、觀測井?dāng)?shù)據(jù)采集、現(xiàn)場調(diào)查等手段,分析了項(xiàng)目區(qū)的地質(zhì)、水文地質(zhì)條件,以水文地質(zhì)單元為基礎(chǔ),得到區(qū)域地下水資源量及節(jié)水增糧項(xiàng)目對(duì)區(qū)域地下水的影響,為訥河市節(jié)水增糧區(qū)域水資源綜合利用提供依據(jù)。取得的主要成果如下:⑴收集整理研究區(qū)域的基本資料,對(duì)研究區(qū)的水文地質(zhì)條件、地下水類型、地下水動(dòng)態(tài)規(guī)律及地下水化學(xué)特征等進(jìn)行分析研究,并進(jìn)行計(jì)算分區(qū)。通過資料分析研究得出,該地區(qū)地下水位維持平衡狀態(tài),無明顯下降趨勢。通過調(diào)查、取樣等分析手段,對(duì)研究區(qū)的水化學(xué)特征進(jìn)行分析,結(jié)果表明,研究區(qū)水質(zhì)滿足灌溉和生活飲用標(biāo)準(zhǔn),飲用水源井綜合評(píng)價(jià)均為良好,灌溉水井中兩處綜合評(píng)價(jià)較差,這兩處均為鐵含量較高,其中龍河鎮(zhèn)青色草原氨氮也超標(biāo),其余幾處均為良好。⑵對(duì)研究區(qū)域的地下水資源量進(jìn)行計(jì)算,結(jié)果為研究區(qū)地下水總補(bǔ)給量為12958.5萬m3/a,平均補(bǔ)給模數(shù)為6.895萬m3/a·km2,可開采為6484.66萬m3。從全區(qū)看,訥謨爾河以北老萊河以東的區(qū)域補(bǔ)給條件較差,訥謨爾河以北老萊河以西區(qū)域居中,訥謨爾河以南區(qū)域補(bǔ)給條件較好。⑶根據(jù)節(jié)水增糧項(xiàng)目取用水方案分析研究,對(duì)地下水位進(jìn)行預(yù)測,并依據(jù)計(jì)算結(jié)果,對(duì)研究區(qū)地下水資源開發(fā)利用程度進(jìn)行評(píng)價(jià),為訥河市節(jié)水增糧項(xiàng)目區(qū)水資源可持續(xù)利用提供一定的科學(xué)依據(jù)。
[Abstract]:Water is the basic material condition for the survival and development of human society. In northern China, many areas and cities in dry and semi-dry areas. Groundwater has become an important or even the only source of water supply. Nehe City is located in the northwest of Heilongjiang Province, is the main food production base in Heilongjiang Province. The unreasonable exploitation of groundwater resulted in the decrease of local groundwater level. Developing the project of saving water and increasing grain puts forward higher requirements for the rational development and utilization of groundwater resources in Nehe City. Therefore, the paper evaluates the groundwater resources of Nehe City and puts forward a plan for rational development and utilization of groundwater resources in Nehe City. The purpose of this paper is to provide scientific basis for groundwater exploitation and utilization in this area. Based on the action of saving water and increasing grain in Nehe city, this paper collects the existing data, collects the data of observation wells, and investigates on the spot. The geological and hydrogeological conditions of the project area are analyzed. Based on the hydrogeological unit, the effects of regional groundwater resources quantity and the project of saving water and increasing grain on regional groundwater are obtained. It provides the basis for the comprehensive utilization of water resources in the area of saving water and increasing grain in Nehe city. The main results obtained are as follows: 1. Collect and sort out the basic data of the research area, the hydrogeological conditions and the type of groundwater in the study area. The dynamic law of groundwater and the chemical characteristics of groundwater are analyzed, and the zoning of groundwater is calculated. Through the analysis of data, it is concluded that there is no obvious downward trend of groundwater level in this area. The results show that the water quality of the study area meets the standards of irrigation and drinking, and the comprehensive evaluation of drinking water source wells is good. The comprehensive evaluation of the two irrigation wells is poor, both of which are high in iron content, and the ammonia nitrogen of the cyan steppe in Longhe Town is also exceeding the standard, and the others are good .2 to calculate the quantity of groundwater resources in the study area. The results show that the total groundwater recharge is one hundred and twenty-nine million five hundred and eighty-five thousand m3 / a, the average recharge modulus is 68,950 m3 / a 路km2, and the recoverable value is sixty-four million eight hundred and forty-six thousand and six hundred m3. The area to the east of Laolai River to the north of Numur River is poor, and the area to the west of Laolai River to the north of Numur River is in the middle. The recharge conditions in the south of the Namur River are good. 3. According to the analysis and study of the water intake scheme of the water-saving and grain increasing project, the groundwater level is predicted and calculated. The degree of development and utilization of groundwater resources in the study area is evaluated, which provides a scientific basis for the sustainable utilization of water resources in the project area of water saving and grain increasing in Nehe City.
