基于BPCC模型的径流对气候波动和覆被变化的响应

为了研究气候波动和覆被变化对中小流域径流的影响,对BPCC分布式水文模型进行敏感参数分析。根据降雨、温度、和归一化植被指数NDVI的变化趋势计算3个影响因子单独和组合变化前后的径流深。对岷江镇江关流域1980—2003年间的计算结果表明:3种因子的综合影响使流域径流减少11.5%;各因子单独作用的贡献率分别为39.3%、45.4%和15.9%,一定变幅下的单位贡献率分别为9.4%、2.4%和12.2%;计算结果显示气候波动(气候因素)与覆被变化(人为因素)的贡献率之比约为5∶1。

新形势下水资源类卓越人才培养实践教学体系的构建

高校扩招后的新形势对本科生的实践教学带来了前所未有的挑战,结合国家水资源行业建设需求和可持续发展战略的要求,在充分体现我校水资源类专业办学特色的基础上,以面向干旱半干旱地区水资源开发利用、培养基础与实践并重、行业特色鲜明、创新能力强的高素质应用型人才为目的,构建了融合基础–实践–特色–创新(BPCC)的人才培养模式和以实验–实训–实习–实践(4S)为主线的阶梯式实践教学体系。该模式以课程体系建设为引导,以阶梯式实践体系为途径,以教学方法与手段改革为支撑,将强化基础、注重地学特色、加强立体化教学实践、保持思维创新的培养思路渗透到人才培养的各个环节,对水资源类专业特色创新人才的培养进行了探索。

Quantitative comparison of semi- and fully-distributed hydrologic models in simulating flood hydrographs on a mountain watershed in southwest China

To investigate the performance of fully- and semi-distributed hydrologic models in simulating the process of transformation from rainfall to runoff in mountain areas, the fully-distributed models Basin Pollution Calculation Center （BPCC） and HEC- HMS are calibrated for the Zhenjiangguan watershed located in the upper stream of Minjiang River Southwest China using streamflow observations at the basin outlet. Semi-automatical optimization method is implemented to both models to improve simulated resuits by removing artificial errors. Based on the consistency of the simulated hydrographs with the observed ones, the statistical coefficients such as the relative error, the probability distribution and the correlation coefficient, are further introduced to evaluate quantitatively the performance of the two models. Analyses indicate that the hydrographs simulated by the BPCC are relatively closer to the observed ones than those simulated by the HEC-HMS in view of the spatial heterogeneity in terrain, soil texture, land cover and meteorological conditions in mountain areas.
