Zhejiang Daxue xuebao. Lixue ban, 2007 对天台大雷山4个不同生境（常绿阔叶林、灌丛、竹林和杉木林）夏蜡梅群体的果实、种子形态变异及其与环境因子的相关性进行了研究.测量的果实和种子12项形态学指标表明，果实和种子的性状以灌丛生境最优、其次是竹林生境、最差的是常绿阔叶林生境.表型性状在群体间和群体内都存在着一定程度的变异，其中群体间的变异系数的平均值从61.71（每果种子数）到7.51（种子厚）.夏蜡梅种子形态较果实形态穗定.单因素方差分析显示，夏蜡梅果实和种子形态在不同生境间差异显著，其中80%以上的变异来源于生境内 ...

野生动物学报, 1997 我们于１９９４年３～８月对安徽省女山湖７种生境繁殖鸟类及群落进行了研究。共记录到繁殖鸟类５１种，生境Ⅶ种类最多，生境Ⅰ和Ⅲ最少。群落种的多样性指数最大的为生境Ⅶ，最小的为生境Ⅲ。多样性平均数控制图可将７种生境分为３组。依据鸟类对生境利用情况和鸟类群落特征对７种生境进行评价和排序，结果是Ⅶ－Ⅵ－Ⅱ－Ⅳ－Ⅴ－Ⅰ－Ⅲ。

甘肃安西极旱荒漠国家级自然保护区野马生境适宜性评价和景观特征分析
野生动物学报, 2023 甘肃安西极旱荒漠国家级自然保护区是我国野马（Equus ferus）重引入及野放项目的重要成员之一，开展生境适宜性评价是制定该物种保护规划的前提和基础。综合考虑植被、地理环境等影响野马生境选择的关键因子，以及道路和放牧等人为干扰因子，在地理信息系统（GIS）和遥感（RS）技术的支持下，采用层次分析法（AHP）确定各评价因子的权重，运用生境适宜性指数（HSI）模型得到野马生境适宜性综合评价分级图并计算各分区面积。同时，利用Fragstats 4.2景观分析软件从斑块水平对其生境进行景观格局特征分析 ...
