ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

The soil fungicide reduces the occurrence of pathogenic fungi in invaded soil and at the same time promotes the recruitment of mycorrhizal fungi and saprophytic fungi by the plants. The addition of biochar to the invaded soil has a negative legacy effect on subsequent invasive plants, while it exerts a positive enhancement effect on native plants ...

以新疆1995、2000、2005及2008年4个时期的土地利用数据为基础,结合水资源分区、SRTM-DEM和数字地貌等数据,分析了基于水资源分区和地貌特征的新疆耕地资源的变化特征,结果表明:①总体上,不同时段各水资源分区耕地空间分布稍有变化,但总体格局保持不变。不同时段各水资源分区的耕地面积有增有减,但增加量远超过减少量,耕地总体呈现出持续增长的趋势,从1995年到2008年,共增加126.39×104hm2。②对比4个时期26个水资源分区的耕地数值、变化和升降形式差异,可将耕地变化形式归纳为上升 ...
