Shuitu Baochi Xuebao, 2007 植被恢复是退化生态系统重建的重要途径，植被恢复过程中物种多样性的变化反映了植被的恢复程度，通过群落调查，研究了太行山片麻岩区植被恢复过程中群落物种多样性特征及其与土壤含水量之间的关系，结果表明：物种多样性指数天然灌木群落〉人工乔木群落。乔木和灌木群落各指数大小为封禁20年〉封禁10年〉封禁5年。6种群落其土壤含水量均偏低，随着封禁时间的加长，含水量略为增加，但天然灌木群落平均含水量稍大于人工群落。不同封禁时间群落土壤含水贯与均匀度指数成正相关，多样性指数与含水量先呈正相关，在封禁20年时，呈负相关 ...

鄂尔多斯遗鸥国家级自然保护区湿地鸟类群落结构及其对水环境的响应
野生动物学报, 2022 2016—2019年对内蒙古鄂尔多斯遗鸥国家级自然保护区的鸟类物种多样性及群落结构进行了调查,同时对水质指标进行了年度监测。保护区共记录到鸟类51种,隶属于9目13科,其中夏候鸟23种,旅鸟24种,留鸟4种。在鸟类区系方面,古北界鸟种1种,广布种50种。湿地鸟类群落物种丰富度、多样性指数和均匀度指数均从2016年开始呈下降趋势,2018年开始回升,但未恢复到初始水平。水质指标测量结果显示,保护区水环境总体质量较差。虽然鸟类多样性和污染物综合指标变化相关性并不显著,但是从总体上看 ...

Studies on the standing stocks, bacterial productivity and bacterivory ratio of heterotrophic bacterioplankton in the Tieshan Harbor and Shenhu Gulf in summer [PDF]
, 2011 微生物（尤其是异养细菌）是微食物环中不可或缺的重要组分，这是近十年来海洋生态学研究中最重要的发现之一。迄今为止，对异养细菌在海洋微食物环和生物地球化学循环中的重要作用已有许多研究，但仍存在一些疑惑。不同生态环境中的细菌现存量和生产力状况如何？细菌生产力和生物量的调控方向是上行控制（营养物质可获得性）还是下行控制（来自于捕食者的摄食压力）？不同海湾细菌二次产量调控机制有何不同？溶解有机质（DOM）怎样通过细菌传递到更高营养级，也就是说有多少细菌产量通过微型浮游动物的摄食进入微食物环中 ...

New Phytologist, Volume 249, Issue 2, Page 764-776, January 2026.Summary Fine roots are critical for soil resource uptake, yet how declining plant diversity alters fine root biomass (RB) and traits remains unclear. We tested how plant functional trait dissimilarity in shade tolerance, drought tolerance, growth rate, and nitrogen‐fixation ability drives variation in root attributes.
