Analyzed the intraspecific and interspecific relationship of Bruguiera gymnorrhiza and Rhizophora stylosa with commonly used niche calculation formula and Hegyi single-tree competition index mode, the results showed that they had extreme similar niche breadth and high value of the niche overlap index.

文章采用常用的生态位宽度、生态位重叠计测公式和Hegyi竞争指数模型，研究木榄和红海榄种内以及种间的相互关系。

The results showed that in the enclosed area in the natural recovery process, the constructive species of Stipa niche width became larger and the dominant populations niche width presented reducing trends and the majority of the remaining population niche width was gradually increasing.

结果表明：在围封自然恢复进程中，建群种针茅的生态位宽度较大，主要优势种群的生态位宽度呈减小趋势，其余大部分种群生态位宽度逐渐增大。

When we were busy protecting the village's cultural relics some villagers came to remind us of the teachers' condition. I used to have a plan and because I'm good at developing EcoTourism I thought maybe I can use some percentages of its gain to make up their salary and invite new teachers coming. Objectively speaking Wayao has good roads, profitable prairie economy if only the society and local government can step up more especially the society but it's always short lived.

我们在这个村进行文物保护的时候，村民也象我们提过这个问题，但我们现在还没有找到一个更好的方式，我初步设想的方式是这样的：因为我比较擅长做生态旅游，如果能把当地村庄的生态旅游做起来，就可以把生态旅游的一部分收入作为教师工资的一部分补贴，这样做是能够请到老师来的，因为从客观条件上来说，它那里的交通是非常好的，生活条件也不差，在藏区算是富裕的地区，基础设施也相当好，主要的问题就是教师的工资，因为政府的财政收入是很有限的，更多的是需要一种社会力量的帮助，社会力量的帮助存在的一个问题就是：它不是一个可持续性的，是短暂的。

The dissertation modifies the model of Holdridge's indexes of lifezone according to the features of the ecological climate of Xinjiang. The influence of the variation of vegetation caused by the climate variation of Xinjiang in recent decades is also analyzed. In recent 40 years, the type of life zone hasn't changed, the area and number of patch changed only. The diversity changed but not too much..That is, diversity of life zone changed in little range, the whole entiroment is still be a rather stable state, whill be goo for desertation expand contrandictorily.

根据新疆生态气候特征和生物地理规律对Holdridge生命地带分类模型进行修正，分析新疆近几十年来气候变化所引起的植被变化对于新疆土地荒漠化的影响。40多年来，新疆生命地带的类型数量并没有产生变化，只是各类型的面积和斑块数的变化，多样性有所波动，但是波动不大，也就是说生命地带多样性的震荡幅度不大，整个生态环境处于一种相对稳定的状态，这种稳定的生态环境状态有利于荒漠化的逆向发展； 7。

Seventhly, we sets up the reaction-diffusion equations about population-resource relationships; Further more, we analyzes these typical conceptual models making use of differential equation theory. The conclusion shows that human with natural environment co-exist conditions when human-environment is conflicting, mutual, predacious, harmonious. The relation both human and environment has to harmonious each other for the population-resource benefit maximum.

在连续时间条件的假设下给出了关于人口与农业生态资源的具有代表性的几种反应扩散方程形式；根据微分方程定性理论，对所建立的几种模型进行分析研究，得出当人类与生态环境处于冲突、互助、掠夺与和谐状态时，双方能长久共存的稳定条件，并得出只有在人口与资源和谐共处的情况下，才能使环境承载力及人类总数达到最大化的结论。

The wild grass, bush community, artificial mixed forest were regarded and natural secondary forest were regarded as the research subject of different stages in the process of ecological construction aimed at soil and water conservation around Napahai Lake in the northwest of Yunnan Province. The change of those community structures was studied by using spatiotemporal substitution method.

在滇西北高原香格里拉县纳帕海周边区域，以荒草丛、自然恢复灌丛、自然恢复高山松次生林以及人工混交林等四种生态系统类型为研究对象，采用时空互代法，视它们为水土保持生态修复过程中不同阶段，研究不同生态系统的群落结构变化规律。

This paper compares international safari and ecotourism in areas like fundamental concepts,activity bases,activity styles,tourist behaviors,and tourist attitudes,etc.,discusses the relationship between international safari and ecotourism,and argues that international safari is a special ecotourist activity characteristic of ad venture and competition and is a tourist model which can develop sustainably.

国际狩猎已成为社会关注的一个热点话题，文中比较了国际狩猎与生态旅游的基本理念、活动基础、活动方式与功能、旅游者行为、态度状况等特征，探讨了国际狩猎与生态旅游的关系，从而提出国际狩猎从性质上应属于具有冒险和竞技特征的特种生态旅游活动的观点，是一种符合可持续发展的旅游模式。

But there was continuous variance among ten species, the strategies of ten species form a continuum.

但是十种植物的生态对策是多种多样的，它们在物种之间又有一定的连续性，并不能将所有的植物生态对策纳入几种主要类型。

Our marine biotechnology development urgently need to address the innovation-based research tools and contents: Controlled ecological experiments with the combination of indoor experiments, carrying out key species life history, experimenting ecological experiments ,measuring the value of the main types of resources and energy gainings, etc.

受控生态实验与室内实验相结合，开展关键种生活史、实验生态实验，测定主要资源种类的比能值、能量收支等，是我国海洋生物技术发展迫切需要解决的创新型研究手段和研究内容；简化食物网研究是有效认识海洋生态系统的新型议题。

Applyed Levins Index corrected by Corwell and Wang gang Index, the niche breadth and niche overlaps of 20 species' in alpine meadow of Bayanbulak were measured at two resource dimension levels.

本文采用Levins提出经Corwell修正指数和王氏重叠指数，在土壤pH值和土壤全盐二维生态因子梯度上，测定了巴音布鲁克高寒草地20种主要植物种群生态位宽度和生态位重叠值。
