昆明市松华坝水源区土壤侵蚀研究
变化环境 土壤侵蚀 水源区 松华坝
2013/9/12
为研究土地利用变化和气象条件变化对云南省昆明市松华坝水源区土壤侵蚀的影响，基于SWAT模型，采用1986~2009年4期土地利用和昆明市1993~2009年气象数据，对变化环境下松华坝水源区牧羊河流域的土壤侵蚀变化情况进行了研究。结果表明，与1986年相比，1995年水源区林地面积增加，耕地面积减少，土壤侵蚀模数减少；2009年，林草面积减幅较大，耕地面积又大幅增加，导致土壤侵蚀模数相对1986，...
随着经济社会的快速发展，赤水河流域治理开发与保护矛盾日益突出。在分析流域基本情况、治理开发与保护现状的基础上，提出了治理开发与保护的总体思想、原则、总体布局以及治理开发与保护措施。同时，有针对性地提出了以该流域为试点，逐步推进流域综合管理和探索建立生态补偿机制的思路、方法与措施。对于正确处理其他流域开发与保护关系，促进流域经济社会可持续发展，具有很强的指导意义。
三峡水库汛末能否顺利蓄水至正常蓄水位关系到长江中下游的用水安全，意义重大。由于三峡上游众多梯级水库也是从汛末开始蓄水，将与三峡水库产生竞争性蓄水问题。为了使三峡水库顺利蓄水和最大程度保证上游各梯级电站的经济效益，在分析长江上游干支流水库汛末蓄水对三峡水库蓄水影响的基础上，根据水能价值原理，提出了不影响三峡水库蓄满的上游水库群蓄水分配方法。所提出的方法可为制订三峡水库及上游水库群汛末蓄水方案提供参考...
为研究山地-平原过渡地区地下水的补给机制，选择两个地质背景各异的地区做对比研究，分析各补给来源对地下水贡献率的空间分布特征及其影响因素。研究表明，大气降水是山地-平原过渡地区最主要的补给来源；河水是河渠附近地下水的主要补给来源；稻田水是稻田分布地区地下水的重要补给来源，但是对整个区域的地下水的贡献率较小；山前侧向补给是山前的某个小区域内地下水的控制性补给来源。大区域的地形、地质背景是影响该区域地下...
２００９年７月－２０１０年６月，采用ｂｂｅ法和分光光度法对千岛湖３个采样点的叶绿素ａ进行了定量分析。全湖叶绿素ａ测定结果，分光光度法显著高于ｂｂｅ法，者存在极显著的相关关系，但个别数据差异较大。相同月份叶绿素ａ测定结果，叶绿素ａ的最大值、最小值都是出现在相同的月份，偏相关分析表明，２种方法测定的叶绿素ａ的月份变化较为一致。相同深度叶绿素ａ测定结果，２种方法测出叶绿素ａ的浓度在各采样点的垂直变化趋势...
