Study on Ecosystem Status and its Evolution in Jiulongjiang River Estuary [PDF]
, 2010 随着社会经济的发展和自然环境的变化，我国的河口生态系统面临着日益严重的压力和一系列生态灾害频发的风险，迫切需要对河口生态系统开展评价，从科学的角度分析生态系统过去、现状、成因、发展趋势，以指导生态系统管理工作。因此，研究河口生态系统状态及其演变具有重要的理论和实际应用价值。 目前，我国对河口生态系统状态的研究和评价的开展尚在探索阶段，还未形成制度化的评价机制、指标体系及评价方法，虽然有少量与河口生态系统相关的研究成果，但长时间序列的河口生态系统评价少之又少。本文构建了河口生态系统PSR模型评价指标体系 ...

喀斯特原生天坑垂直梯度上植物多样性特征——以云南沾益天坑为例 [PDF]
, 2018 规模宏大的地表负地形——喀斯特天坑具有巨大的容积和陡峭圈闭的岩壁,在坑底形成异于坑外的独特微生境,是研究物种组成和多样性的理想场所,但目前鲜少对喀斯特天坑植物群落的生态过程及其空间变化特征进行探讨。本研究以云南沾益大毛寺原生天坑植物群落为研究对象,通过游动分割窗技术以及边缘效应值、边缘效应强度和β多样性指数的计算,对原生天坑\"坑边缘—坑壁—坑底\"的生态交错带进行定量判定,探讨垂直环境梯度上植物群落物种多样性变化特征及天坑内外物种多样性边缘效应特征。研究结果表明,原生天坑\"坑边缘—坑壁—坑底 ...
