In this paper, the 3-D finite element relocating mesh method is used to calculate the temperature field and the thermal creep stress field of spillway dam and mid level outlet dam in certain roller compacted concrete gravity dam, sensitivity analysis have been down with different parameters, such as placing temperature, the location of cooling pipe, cooling temperature, time for water supply, ascended-layer of concrete, intermissive time and different placing time, and the commendatory construction scheme have been put forward in such analysis; according by the test result on the two scheme of concrete aggregate combination (basalt as coarse aggregate and limestone as fine aggregate, basalt as coarse aggregate and basalt as fine aggregate), simulation analysis on temperature field and thermal creep stress field of the commendatory construction scheme have been down, and analysis have also been down on temperature field and thermal stress field of the two different aggregate combination, the result indicates that the spillway dam and mid level outlet dam which adopted these two aggregate combination can both satisfy the require of design crack resistance in concrete, furthermore limestone as fine is better than basalt as fine aggregate; the effect of summer water storage and winter water storage on the temperature field and thermal stress field have been analyzed, comparing with winter water storage, in summer water storage scheme the maximum tensile stress at abnormal concrete in upstream fill is decreased by 0.1～0.3MPa and there are no evidence change of the maximum tensile stress at other parts, which indicate that summer water storage is avail for the crack resistance of upstream fill; according to the simulation calculating result and comparing temperature simulation calculating results and temperature controlling measures of some similarity projects both completed and construction, synthesis appraise have been carried to the design temperature controlling measures of dam, and the temperature controlling measures of this project have been brought forward, all these have great reference value on the design of temperature controlling measures and the optimization of the construction scheme.

本文采用三维有限元浮动网格法仿真计算程序，对某碾压混凝土重力坝的溢流坝段和中孔坝段分别进行了三维有限元温度场和温度徐变应力仿真计算分析，对浇筑温度、冷却水管的布置方式、冷却水温、通水时间、浇筑升程和间歇时间、不同开始浇筑日期等参数进行了敏感性分析，在此基础上提出了推荐的施工方案；根据两种骨料方案(玄武岩粗骨料+灰岩细骨料方案；玄武岩粗骨料+玄武岩细骨料方案)的混凝土性能试验研究成果，对推荐的施工方案进行了温度场和温度徐变应力仿真计算，并对比分析了两种不同骨料情况下的温度场和温度应力，结果表明溢流坝段及中孔坝段采用上述两种骨料均能满足混凝土的抗裂设计要求，且灰岩细骨料优于玄武岩细骨料；计算分析了夏季蓄水和冬季蓄水对坝体温度场和温度应力的影响，夏季蓄水方案与冬季蓄水方案相比，坝体上游变态混凝土区域最大拉应力小0.1～0.3MPa，其他部位最大拉应力无明显变化，夏季蓄水对坝体上游面混凝土的抗裂有利；根据仿真计算成果并通过比较国内一些已建和在建的类似工程的温度仿真计算成果及采取的温控措施，对大坝的设计温控措施进行了综合评价，并提出了该工程的温控措施，对温控设计和优化施工方案具有重要参考价值。

Effectiveness scarce, demand assignability is a value of the four basic elements, demand for real estate and commodities need to have the capacity to pay, we will not, the effectiveness of commercial housing is scarce in nature and that consumers do not have sufficient purchasing power, the market value can not be achieved, the current real estate market demand can be broadly divided, using the minimum requirements, the public demand for improved housing, urbanization process needs field and offshore demand, the demand for investment or speculative demand and the housing problem is livelihood security, the need to increase public finance, but this is the need, not demand.

效用稀缺，需求可转让性，是价值构成的四个基本要素，需求是对房地产商品有需要而且具有支付能力，两者缺一不可，商品房具有效用和稀缺性，消费者没有足够的购买力，市场价值就不能实现，当前房地产市场的需求大致可分为，动拆迁的需求，市民住房改善的需求，城市化过程中的需求，外地和境外的需求，投资需求或者是投机需求，住房保障问题是民生问题，需要公共财政加大力度，但这是需要，不是需求。

Based on the eco- environment function, confirmed the constitution of eco- environment water demand(including the inside of the watercourse.and the ecological water demand of the outside of the watercourse such as ecological water demand of economical crop, of lake or reservoir and of cities.).③Analyzing the physical geography, hydrography, economy characteristic and water resource status, getting the proper calculation method. The Tennant applied to the eco- environment water demand of inside of the watercourse, woodland minmum eco- environment water demand calculation method applied to the eco- environment water demand of woodland, water ration method applied to farmland the eco- environment water demand, water evaporation method applied to the reservoir eco- environment water demand.

本文以流域生态环境需水为主要研究对象，因此重点阐述了流域生态环境需水量的分类和计算方法；②通过分析流域生态系统构成与流域生态环境功能，并分时段和河段考虑，确定了桃花江流域生态环境需水量的组成，即包括维持现状河道生态环境功能现状的现状生态环境需水量与流域生态环境改善的生态环境需水量，前者包括河道内生态环境需水量(维持河道基本生态功能需水量、维持河道自净稀释功能需水量、补充地下水水量及美化流域景观娱乐需水)与河道外生态环境需水量(流域内植被、森林、农田的需水量和与河道相连的池塘、水库等的需水量)；后者还包括为治理改善流域生态环境而拟规划林业生态建设所需水量；③对桃花江流域的自然地理、水文地质和社会经济特征以及水资源现状及其主要生态环境问题进行了综合分析，提出了适合桃花江流域的生态环境需水量计算方法，即采用Tennant法计算河道内生态环境需水量，采用林地最小生态环境需水量法计算林地生态环境需水量，采用需水定额法计算农田生态环境需水量，采用水面蒸发法计算水库、池塘生态环境需水量。
