以颗粒状和粉末状膨润土防水毯(GCLs)为对象,运用GDS (global digital systems)全自动渗透仪开展渗透试验,研究CaCl_2溶液作用下GCLs渗透性能的温度效应,初步探讨其机理。试验表明:当水化液为0.05mol/L的CaCl_2溶液时,两种GCLs渗透系数随温度升高呈现增大趋势;当水化液为去离子水时,颗粒状GCL渗透系数随温度升高而减小,粉末状GCL渗透系数随温度升高而

Land surface area estimation can provide basic information for accurately estimating vegetation carbon storage under complex terrain. This study selected China, a country dominated by mountains, as an
The spatiotemporal landscape heterogeneity implies multiple biodiversity mechanisms across scales, and the cross-disciplinary studies between landscape ecology and biodiversity are becoming a new rese
蒙古沙拐枣(Calligonum mongolicum)是中国干旱、荒漠地区主要的防风固沙植物,预测该气候变化对其地理分布范围的影响,对中国荒漠化防治工作具有指导意义。采用获得的蒙古沙拐枣108个种群分布数据和22个气候环境因子数据,利用最大熵(MaxEnt)模型软件预测蒙古沙拐枣在当前、2041—2060年及2061—2080年在中国干旱区的潜在地理分布,探究气候变化对该物种分布的可能影响。结果
Understanding the underlying ecological processes that control plant diversity within(α-diversity) and among(β-diversity) forest gaps is important for managing natural forest ecosystems, and it is als
Species abundance and habitat distribution are two important aspects of species conservation studies and both are affected by similar environmental factors. Forest resource inventory data in 2010 were
Understanding biogeographic patterns and the mechanisms underlying them has been a main issue in macroecology and biogeography, and has implications for biodiversity conservation and ecosystem sustain
Urbanization can profoundly influence the ecosystem service for biodiversity conservation. However, few studies have investigated this effect, which is significant for maintaining regional sustainable
