Shuitu Baochi Xuebao, 2000 研究了自然封禁条件下亚热带地区因水土流失导致的退化红壤肥力恢复性能与土壤性质的关系。结果表明，影响退化红壤肥力恢复主要有水分因素和养分因素，其中水分因素决定了土壤肥力能否自然恢复，对于土层浅薄、砂化严重的土壤，由于蓄水能力极低，季节性干旱使植被和土壤肥力难以自然恢复。土壤肥力的恢复还与土壤本身的养分状况存在着一定的联系，养分较高的土壤，料易恢复植被，促进土壤肥力的提高。

Functional Ecology, Volume 39, Issue 2, Page 635-652, February 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Invasive plants are a major cause of the global biodiversity crisis; it is therefore crucial to understand mechanisms that contribute to their success. South‐western Australia is a global biodiversity hotspot with extremely low soil phosphorus (P) concentrations.

Review of Policy Research, Volume 41, Issue 6, Page 985-1016, November 2024.Abstract Sustaining agricultural production in arid and semi‐arid regions is of paramount importance to food security, geo‐political independence, and social stability. In this context, it is vital to understand the effectiveness of policies. In this article, we aim to answer the question of what role the state and its policies play for soil protection

Geographical Variation in Vegetative Growth and Sexual Reproduction of the Invasive Spartina alterniflora [PDF]
, 2015 生物入侵是全球变化的重要内容，对全球经济和环境产生严重影响，并威胁生态系统的多样性。明确生物入侵发生的过程和机制可以有效地防控入侵生物带来的危害。繁殖是入侵种从定居到其后扩张过程中的一个重要的内在因素，进而可能影响入侵的成功。在入侵种扩散并占据广阔的地理分布区过程中，表型可塑性可能起到关键作用。揭示入侵种繁殖和表型可塑性在变异及其与环境因子的相关关系，对阐明外来物种的入侵机制和预测其分布具有重要的意义。互花米草原产美国大西洋沿岸和墨西哥湾，于1979年从美国引入中国。经过30多年的入侵和扩散 ...

Shuitu Baochi Xuebao, 2005 人类干扰所造成的土地利用和植被的镶嵌化分布及地貌特征等影响着土壤养分的空间分异,黄土丘陵沟壑区土壤退化严重,使得土壤特性对其环境因子的变化更加敏感。以横山县为例,从两种尺度上,利用野外调查,实验室分析和典范对应分析(CCA),得到不同尺度下(小流域尺度和县域尺度)土壤理化性质对环境因子的响应。结果表明,坡度是影响土壤养分的重要影响因子,小流域尺度上,坡度和土壤养分、土壤黏粒含量成正相关;县域尺度上,坡度和主要土壤养分等呈负相关。而海拔高度和坡向对土壤养分的影响仅次于坡度,在不同尺度上也有差异 ...

Urban Soil and Its Relationship to Landscape Planting [PDF]
, 2003 城市土壤是影响城市绿化植物生长的重要环境因子。从城市土壤的物理化学特征如结构、土壤容重和紧实度、城市土壤的水分供应、土壤有机质与养分含量、土壤酸碱度、土壤次生盐渍化和盐基饱和度等角度讨论了城市土壤与城市绿化植物生长之间的关系。城市绿化应该从土壤抓起。Soil is one important factor influencing the growth of plant species in the urban.

Relationship between mangrove distribution and soil characters at Dongzhai Harbor and Qinglan Harbor, Hainan [PDF]
, 2008 以海南东寨港和清澜港红树林为研究对象，在东寨港演丰镇、三江镇和清澜港文昌的海岸从水缘至陆缘设置样带，于每样带按一定间距设置调查位点，在每位点记录物种出现情况，并分析部分样带土壤的理化性质和生化性质。比较东寨港和清澜港土壤底质、潮位等因素对红树林分带的影响。 研究结果表明，所调查的红树植物物种从低潮滩至高潮滩分布的序列为：白骨壤一般为先锋植物，但由于适应生境能力强，在不同滩位和潮带均可见；正红树、红海榄、杯萼海桑、海桑为前沿向海带；秋茄、桐花树、木榄、海莲、角果木、瓶花木、榄李位于中间林带；木果楝、老属簕、
