江西退化红壤区3种森林恢复模式的枯落物和土壤表层水文功能研究
为探讨退化红壤区植被恢复对枯落物层及土壤层的水源涵养功能影响,进一步揭示退化生态系统植被恢复的功能效应,采用室内浸水法和环刀法分别测定了3种恢复模式(木荷纯林、马尾松纯林、马尾松间伐补木荷林)的枯落物层与0—20 cm土层的持水能力。结果表明:(1)马尾松纯林的枯落物层蓄积量最大(7.91 t/hm2),持水能力最强(15.39 t/hm2),但持水率不如木荷纯林(246.69%)。(2)马尾松纯林的枯落物层有效拦蓄量和最大拦蓄量均为最大(7.75,10.02 t/hm2),木荷纯林的最小(3.83,5.

The Role of Public Finance to Address the Global Finance Gap for Drinking Water Services
ABSTRACT Meeting SDG target 6.1 for drinking water requires addressing the finance gap between the funds available from tariffs, taxes and transfers, and the life‐cycle costs of sustaining these services. While there are li‐mitations to applying repayable finance to address this gap, governments can be well suited to support both drinking water ...

Experiment and modeling of soil-water characteristic curve of unsaturated residual soil [PDF]
土-水特征曲线是指基质吸力与含水率或饱和度的关系曲线。土-水特征及其相关数学模型可用于非饱和土性质如渗透系数和抗剪强度模型的建立。通常,土-水特征曲线仅有脱湿曲线。笔者详细讨论了初始含水率、干密度、竖向应力及干湿循环对脱湿曲线的影响。采用滤纸法测试了厦门地区残积土的土-水特征曲线(SWCC)及滞回环。结果表明,初始含水率对SWCC影响较小,最优含水率干侧试样SWCC的进气值小,滞回环小;湿侧试样的进气值大,滞回环大;最优含水率试样的滞回环居中。初始干密度对SWCC有显著影响,低干密度试样SWCC进气值小,

Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks
Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

庐山杉木林与黄山松林的土壤层水源涵养能力和土壤侵蚀敏感性探究
森林的水土保持效益包含水源涵养能力和土壤的侵蚀敏感性,为探讨基于坡面尺度林分因子对水土流失的影响,进一步揭示森林植被的水土保持效益机制,采用环刀法、EPIC模型等分别计算黄山松林、杉木林的水源涵养能力和土壤侵蚀因子。结果表明:(1)黄山松林的土壤容重在垂直剖面无明显差异,变化范围为0.66~1.10 g/cm3;杉木林的容重(0.92~1.21 g/cm3)则呈现中下层(40-80 cm)大于中上层(0-40 cm)。黄山松林上层(0-20 cm)土壤的最大持水量极显著大于杉木林。土壤的毛管持水量 ...
