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 aberrance itself is a kind of active research, which not only lengthways reviews the developing state of television art but also breadthwise compare the aberrant relationships between traditional arts and television arts, in order to find out aesthetic rules. The comparative method I adopt accord with the subject, appropriate revealing the active research characteristic.

电视研究是一种动态的研究，国家政策、经济发展、技术革新等因素都影响着电视的传播，电视艺术生态在呈动态发展，电视艺术美学也如此，&变异&问题本身就是一种动态的研究，它从纵向考察电视艺术的发展状态，同时还通过横向比较各传统艺术与电视艺术之间的变异关系，最终寻找出电视艺术的美学规律，而我所采用的比较的方法与影响研究是很符合这个选题的，这恰恰显示出了动态研究的特性。

There are about 100 species plants in the wetland, and the majority is herbage and frutex. These plants included Polygonum hydropiper, Nelumbo nucifera, Annua Linn, Phragmites communis etc. At the same time, there are also 48 species animals, which belong to 30 families, and these animals included Ciconia ciconia, Cygrus cygrus, Platalea leucorodia, Meles meles etc.

湿地内有高等植物近100种，其中草本和灌木占大多数，典型的如水蓼、莲藕、早熟禾、芦苇等；在此栖息的动物有5纲共18目30科48种，具有代表性的如黑鹳，大天鹅、白琵鹭、狗獾等，是铜川市重要的水源补给地和湿地保护区，对于当地生态环境和经济社会可持续发展意义重大。

In this paper, the decolorization of acid mordant dyes on fresh MnO 2 and the main effect factors were investigated.

本文主要报道了一种用于染料废水处理的新型材料即新生态MnO2 及其对三种酸性媒介染料染色废水的脱色作用及影响脱色效果的主要因素。

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。

Vegetation types in mountainous area of West Lake4 groups of vegetation type, 7 vegetation types, 14 formation groups and 25 formations were present in mountainous area of West Lake, according to taxonomic approach and divisory principle in Vegetation of China and Forest of Zhejiang.

西湖山区森林植被类型根据《中国植被》和《浙江森林》的划分原则和分类系统，采用高级分类单位以生态外貌为主、中低级单位采用优势种和标志种相结合的原则，把西湖山区的各类森林划分为4个植被型组、7个植被型、14个群系组和25个群系。

We analyzed the relations of plant ecological type groups and community biomass and environment changes in the grassland communities of Leymus chinensis as edificator along Northeast China Transect.

Paecilomyces cateniannulatus,an entomogenous fungus and one of the predominant species of the fungi in a Masson s pine plantation ecosystem,plays an important role on forest pest control.

中文摘要：环链拟青霉是一种虫生真菌，是皖南宣城敬亭山马尾松林生态系中的优势种，在松林控制害虫起到了至关重要的作用。

Basing on our early stage research work about collection and description of sugarcane germplasm and the aided project of Yunnan Natural Science Fund (2001 C0015Q), the wild species Erianthus fulvus, which has good characters, cold-resistant, drought-resistant, higher Brix and less chromosome number, was utilized for the first time through intergeneric hybridization with sugarcane cultivar. Its F_1 hybrids were appraised with some new techniques and methods for germplasm enhancement.

本研究在课题组考察采集和保育鉴定甘蔗野生种质资源的前期工作基础上，依托云南省自然科学基金资助项目(2001C0015Q)，首次利用具有特异优良性状(抗旱、耐寒、锤度高、染色体数目少)的蔗茅野生种与甘蔗栽培种或品种进行属间远缘杂交，扩大甘蔗遗传多样性；采用新技术、新方法对蔗茅杂种F_1代材料进行早期鉴定评价研究，筛选具有育种价值的新种质，为进一步选育生态适应性广、抗逆性强、丰产高糖的甘蔗新品种奠定物质基础。
