By using red blood cell broken-up solution,proteinase K and RNase,total DNA with high quality was extracted from the egg membranes in the incubated eggshells of two pheasant species,Reeves's Pheasant Syrmaticus reevesii and Ring-necked Pheasant Phasianus colchicus from Dongzhai Nature Reserve in Henan Province.

本实验以河南董寨自然保护区白冠长尾雉和环颈雉已孵化的卵壳为材料，利用红细胞破碎液、蛋白酶K及RNA酶等试剂，对卵壳膜内的总DNA进行了提取，建立了一种提取高质量DNA的新方法。

And the author summarized the main identifiable features at the genera level. Some pictures of new reported species have been drawn. In the thesis, the author studied its geographical elements, compared the species abundance, the generic similarity coefficient, the phytogeographical elrments,and analyzed the floristic spectrum using the method of Principal Component Analysis . According to the comparison between the area of Pangquangou Nature Reserve and other 8 areas, The abundance of the bryophytes of Pangquangou Nature Reserve lower than the other 8 area.

通过物种丰富度、属相似系数、区系谱主成分分析、区系地理成分分析等多种方法与内蒙古七老图山、山东崂山、福建鹫东麓、新疆东部天山和吉林省长白山、河南云台山、河北小五台山、滦河上游地区8个地区的苔藓植物区系进行了比较，发现庞泉沟自然保护区苔藓植物物种丰富度最低。

This paper, based on the land utilization change data during 1997 to 2005, applies the information entropy and equilibrium theory to study the temporal-spatial changes in land utilization structure in Lingshui county, with results indicating: a first slow and then a fast rise in information entropy of land utilization structure in Lingshui county and a general trend of rising homogeneity in land utilization structure; the information entropy of land utilization structure ascends from NW to SE, where can be divided into five regions, ecological protected area, resort area, farmland protected area, ecological agricultural construction area and comprehensive industrial developing area; the economic factors and populational structure play a key part in land utilization structure changes via principle componential analysis.

基于陵水县1997-2005年土地利用变更数据，利用信息熵和均衡度的基本原理，对陵水县土地利用结构的时空变化进行实证分析。结果表明：1陵水县1997-2005年土地利用结构信息熵和均衡度呈现先缓慢增长、再加速增长的变化过程，总趋势是土地利用结构的均质性逐渐增强；2）陵水县土地利用结构信息熵从西北向东南逐渐递增，依次可分为生态保育区、风景旅游区，基本农田保护区、生态农业建设区和综合产业发展区5个区域；3）利用主成分分析，经济因素和人口结构对陵水县土地利用结构变化影响重大。
