摘要
坪上应急引水工程是山西六大水利工程之组成部分,是山西兴水战略的重要组成部分。坪上泉岩溶水是坪上应急水工程的引水水源。由于该项目的供水目标为忻府、定襄和原平,保证率要求很高。供水工程水源地的建立直接关系着供水区国民经济的可持续发展,以及百万人民的安全用水,因此,山西坪上泉水资源量评价及基于SVM理论的岩溶泉流量预测模型研究具有重要的现实意义和长远的战略意义。
     本文在前人研究的基础上,通过对研究区水文、气象、地质、地貌和水文地质条件分析,根据系统理论划分了泉域岩溶水子系统,即甲子湾泉子系统、李家庄泉—坪上村泉子系统、水泉湾泉—段家庄泉子系统和水头沟泉子系统。建立了泉域水文地质概念模型,将泉流量的主要影响因素概化为大气降水、河水渗漏补给和人工开采。
     本文简述了支持向量机基本原理,针对支持向量机(SVM)预报模型的智能化程度高、人工干预少,可随变量实测资料的增加,通过自学习来自动调整参数,使模型不断贴近实际,以及操作简单易于工程管理部门实际应用的特点,结合评上泉实际,建立了基于SVM理论的坪上岩溶泉流量预报模型,并针对影响因子对泉水流量时序性作用特征,优选了最佳时间序列长度,确定了最佳核函数,制定了模型预报流程。因此该项研究为引水工程未来数字化管理,为引水工程可供水量预报和供水区的多水源优化配置奠定了基础。
     本文还依据坪上泉域地处山区的特点,确定泉水资源量计算方法,即以排泄法为主、补给法校核。计算得:泉域1956~2006系列多年平均岩溶地下水资源量为15200万m3/a;泉域岩溶地下水可利用资源量采用了理论频率分析法,计算结果表明:坪上泉岩溶地下水年可利用资源量为7064万m3/a,地下水资源可采系数为0.465,岩溶水现用量仅占可利用量的4.3%,为有潜力开发区。
?Pingshang jury diversion works is component part of the six large irrigation works in Shanxi province.It is important part of strategy plan for build water conservancy project in Shanxi province.Pingshang karst water is water souce of Pingshang jury diversion works.This project will supply water to Xinfu,Dingxiang and Yuanping.The higher reliability of this project is needed.The construction of the water source is related to sustainable development of national economy in this area and safety water for million people.Therefor the assessment of karst water resource of Pingshang spring and the research of forecast model of karst spring discharge based on SVM theory are very important in practical living and economy development policy.
     In this paper based on research results of predecessors the huge data about hydrology,meteorology,geology,geomorphology and hydrogeology are analysed.The karst water system in this area are divided into a certain numbers of subsystems according to the system theory.That is subsystem of Jiaziwan spring,subsystem of Lijiazhuang spring—Pingshangcun spring,subsystem of Shuiquanwan spring—Duanjiazhuang spring,and subsystem of Shuitougou spring.The conceptual hydrogeology model is established.The main effective factors on karst discharge are summarized as rainfall,replenishment by river leakage and human exploitation.
     The primary theory of SVM is explained briefly.Because of the SVM forecast model has high intelligence,less human participation,with the observation data increasing the model will modify the parameters automatically,so that to approach the real case,it is easier for operation and easier to use for the department of engineering management,so the discharge model of Pingshang karst spring is established by SVM theory.According to effective factors on spring discharge in time oder,the optimum time oder length and the optimum kernel function are decided.And the process of forecast is decided.The base for diversion works management digitizing,forecast of quantity of water feed and optimization of desposition scheme of water resources in this area is established by this research results.
     Because of the Pingshang spring located at mountain area so the computing method for the water quantity evaluation are carefully considered.The drainage method is main method.And the evaluated results are checked by replenishment method.The evaluated results show that the mean value of the underground karst water during 1956 to 2006 is 152 million m3/a.The theoretical frequency analysis is used to evaluate the useable quantity of underground karst water in this spring area.The evaluated results show that the useable quantity of underground karst water in Pingshang is 7.046 million m3/a per year.The useable factor is 0.465.The current consumed water quantity is 4.3 percent only.So this spring area has great potentialities for exploitage.
