新疆玛纳斯河流域农业水资源可利用潜力分析

结合新疆玛纳斯河流域水文水资源、种植结构和节水技术发展等资料,从开源、节流两方面对流域近期(至2010年)、中远期(2010-2030年)农业水资源极限潜力、可挖掘潜力进行了估算。结果表明,就目前水资源的利用水平和开发趋势,玛纳斯河流域未来农业水资源的主要利用途径是开源与节流相结合,以节流为主。全流域尚有的农业灌溉水资源极限潜力为10.75×10⁸m³,近期农业水资源可挖掘潜力为2.13×10⁸m³,其中开源增水潜力0.40×10⁸m³,占18.8%,节流增水潜力1.73×10⁸m³,占81.2%;中远期农业水资源可挖掘潜力5.33×10⁸m³,其中开源增水潜力1.12×10⁸m³,占21.0%,节流增水潜力4.21×10⁸m³,占79.0%。该研究对区域制订节水灌溉规划及水资源系统优化配置具有重要参考价值。     

渭河流域生态环境对野鸭数量分布的影响

环境是动物生存的基础，人类的活动对环境所造成的影响，直接导致动物种群数量的变动。通过渭河咸阳段气候、水质、水域面积、植物等环境因素的改变对野鸭数量分布影响的调查，表明环境的恶化导致了动物的生存受到威胁，数量减少，分布区域缩小。随着环境保护意识的增强，渭河流域的水土流失，水质污染、退耕还草等环境问题逐渐得到解决，动物的生活环境不断得到改善，其种群数量、分布范围随之增加。     

Angler survey contributes to socially acceptable modification of harvest regulations to preserve cutthroat trout fishery in Snake River,Wyoming, USA

This is a case study that describes a survey of anglers that was used to assist in modifying fishing regulations for indigenous trout in the Snake River, Wyoming. A mail survey of anglers who purchased 1991 Wyoming fishing licenses in the two counties adjacent to the Snake River was conducted during fall 1992. Differences in angler preferences were noted between anglers who purchased licenses in two adjacent counties with different socioeconomic structures, as well as between residents and nonresidents in each county. Anglers who purchased licenses in Teton County, where there is extensive tourism and immigration by relatively wealthy residents, tended to be more specialized and less harvest oriented. Anglers in Lincoln County, which is largely agricultural and has substantially less tourism and immigration of residents, tended to fish in many different ways and indicated more desire to harvest fish. Anglers from the two counties segregated themselves; those from Teton County primarily used the upstream portion of the study reach, and those from Lincoln County primarily used a short downstream portion of the reach. Modification of fishing regulations to reduce harvest of spawning-size cutthroat trout in the Snake River probably was acceptable to most anglers due to spatial segregation and their attitudes toward harvest.The unit is jointly supported by the University of Wyoming, the Wyoming Game and Fish Department, and the National Biological Survey.     

OPTIMIZATION MODELING OF A NEW FACILITY FOR THE CALIFORNIA STATE WATER PROJECT1

ABSTRACT: A non-linear optimization model is applied to the California State Water Project (SWP) and portions of the Central Valley Project (CVP). The model accounts for the major hydrologic, regulatory, and operational features of both projects. The model maximizes long-term SWP yields over a 70-year period, using a quarterly time step. The potential for increased yield associated with a proposed facility improvement is evaluated with the model. The proposed facility is an extension of the Folsom-South Canal, which would allow water to be conveyed from the American River below Folsom Reservoir into New Melones Reservoir on the Stanislaus River or into the California Aqueduct. Model results indicate that extension of the Folsom-South Canal has the potential to increase SWP yields by 13 percent.     

人为泥石流灾害严重等级的定量模糊综合评判

根据神府－东胜矿区人为泥石流的调查分析，选择１５个因素（含５个主控因素）作为其严重程度的评价因子，确定了四值逻辑（严、中、轻、否）评判的定量标准。应用模糊综合评判和分层定量模糊综合评判两种方法对该煤田６５条泥石流沟的严重等级进行综合判别，准确性达９３．１％，它为保护该地煤田建设和工农业生产提供了重要的科学依据。
