The results indicated that there are has 21 kinds of alien invasive plant species which belonging to 21 generas and 13 families in Xiushan region, the alien plants has an important influence on the area where change farmland into woodland and the farm land that the condition of being unseeded, and the total coverage of the alien plant mostly reached 100%.

11入侵种是指在引入地建立了种群，改变或威胁本地生物多样性，对生态系统的结构造成了明显的损害和影响的外来种。u 1入侵植物就是指具有从原来的分布区域扩展到一个新的地区，在新的区域里其后代可以繁。。。。。。

The result indicated that: with the change of ecological factors and intensification of human activities,strong stability of grassland community structure of the local alpine meadow type along the highway in this region was found,proportion of medium xerophilous、rhizomous grass increased;alpine grassland community had relatively low stability,grassland community successed naturally to adapt to the new environment;...

结果显示：随着生态因子发生变化和人类活动的加剧，该区公路沿线高寒草甸类草地群落结构表现出了较强的稳定性，中旱生耐旱的根茎型禾草比重有所增加；高寒草原植物群落稳定性相对较差，草地群落为适应新的生境而发生了自然演替；沼泽化草甸亚类草地植物群落中群落伴生种的种类增加，优势种嵩草属植物在群落中的比重有所下降。

The mangrove species concerned were five: Bruguiera gymnorrhiza, Kandelia candel, Bruguiera sexangula, Bruguiera sexangula var. rhynchopetala and Avicennia marina.

本文首次对全国范围内的木榄种群进行了遗传变异和生态分化的研究，并且用等位酶技术和方法首次对红树科木榄属三种现存的种类进行了种间亲缘关系的鉴定，尝试对种群的分布及建立机制进行了探讨。

The result showed that Imperata cylindrical, Digitaria sanguinalis, Erigeron acer Xanthium sibiricum and Hedyotis auricularia are the species with high tolerance to heavy metal pollutions adapted to the adverse conditions of wastelands. These species can be used as pioneer plants for recovety of the vegetation in the manganese-mined wastelands. The individual event pollution index of the heavy mentals, compared to their background values are higher than 2, with Pb as an exception, indicating that the soil in these areas has been contaminated and that Mn and Cd are the elements creating most serious pollution problems.

结果表明，白茅、马唐、飞蓬、苍耳、耳草对重金属有较强的耐性，而且能适应废弃地的不良环境，可作为锰矿废弃地生态恢复的先锋植物；用3种不同的背景值对废弃地土壤重金属污染程度的评价结果是一致的，除Pb外，5种重金属元素单项污染指数均大于2，表示被污染，其中以Mn、Zn、Cd污染最为严重。

Has also been considered during the revision.More than 1,100 specimens from 11 herbaria worldwide have been examined. After having studied the characteristics, phenology and ecological habit, we have gotten the morphological figures of each species. The characteristics of the disputed species have been studied in detail and have been quantitatively analyzed though scatter-map.

查阅和借阅了2个国家11个标本馆1100余份南五味子属标本，对世界范围的南五味子属种类作了整理，描绘了每个种的性状特征、物候期、生态习性，绘出了形态线描图，讨论了与其近缘属种间的关系；对在分类学上有争议的种类进一步进行解剖和测量，详细记录枝、叶、花、果实、种子等的形状、大小、数目、颜色、毛被等数据或信息，绘制散点图，对各种性状作定量研究，进行分析、归纳与分类。

Aimed at the study of Lauraceae system classification in domestic and overseas,genetic diversity and genetic variation between Cinnamomun micranthum Hayata natural populations and Ex-situ conservation poputations and relationship among Its Close Relative Species of Cinnamomum camphora Presl,Cinnamomum burmannii(C.G.etTh.Nee) Bl,Phoebe bournei Yang. Litsea subcoriacea Yang et P.H.Huan. Neolitsea aurata Koidz,Lindera communis Hemsl and Persea Americana Mill.were studied by inter-simple sequence repeats molecular marker.The research aimed at genetic variation between Cinnamomun micranthum Hayata populations,so that can offer the molecular theoretic and practical method for conservation and utilization of Cinnamomun micranthum Hayata populations.

针对目前国内外对樟科植物系统分类的研究现状，本研究采用ISSR分子标记技术对樟科沉水樟天然居群和迁地保护居群的遗传多样性进行研究，从分子水平上分析沉水樟种群的生态遗传及其遗传变异规律；同时利用ISSR分子标记技术比较沉水樟及其近缘种香樟、阴香、闽楠、桂北木姜子、新木姜子、香叶树、鳄梨在分子水平上的亲缘关系，揭示这些树种在樟科植物系统进化中的作用与地位，探讨沉水樟及其近缘种的遗传多样性及其分化格局，为樟科植物的系统分类提供分子水平的依据。

Themain results are as follows:(1)The utilization-oriented silvicultureshould be regarded as a silvicultural regime or system,that can bestsatisfy the special economic,social or ecological demand for a given regionwith lowest cost and fast speed,using specifically oriented,systematic andadvanced technical measures on the basis of characteristics of tree species,natural and economic conditions and local technical and development levels.

主要研究结果如下：(1)定向培育应该做为一种森林培育制度来对待，即定向培育是根据经济、社会和生态上的特定要求，确定相应的培育目标，然后根据造林地区和造林地的条件，造林树种或树种组合的特性，以及当地经济和技术水平，采用相应专向，系统、先进、配套的培育技术体系，以可能的最低成本和最快速度，达到定向要求的一种森林培育制度。
