The ecotype consumption is a kind of consumption mode which accord with environment rule.

生态消费是一种生态化的消费模式，生态消费对于传统消费方式的超越和变革决定了它不是一般意义上的问题，而是关系到人类活动的重大社会问题。

Therefore, we should change the traditional consumption mode, build up a kind of consumption mode which accord with environment rule—— ecotype consumption mode.

为此，必须改变传统消费模式，建立一种符合生态规律要求的、生态化的消费模式——生态消费模式。

This paper based on reviewing ecological planning and discussing briefly six ecologi-cal planning modes puts forward that the best lodestar of ecological planning is landscape ecology,and the ultimate goal of ecological planning is sustainable devel-opment.

通过对生态规划的产生及发展过程的回顾和对6种生态规划典型模式的初步探讨，揭示出生态规划的最佳指导思想是景观生态学；生态规划的最终目标是可持续发展。

Most importantly, our team are famous for much research on ecology, physiology,molecular phylogenesis of bats at home and abroad, we have gained much originative result in this field, and we firstly found and studied the third piscivorous bat, Myotis ricketti.We provide evidence that the species Myotis ricketti is piscivorous, and close negative relationships were found firstly within Rhinolophidae and Hipposideridae between call frequency and ear length. Some species of taxology status in rhinolophidae were studied by molecular phylogenesis; phylogenesis relationship between rhinolophidae and hipposideridae and different populations of miniopterus schreibersii were also studied; we also studied Social structure of Tylonycteris pachypusa and T. robustula and the isolating mechanisms of ecological niches.

在蝙蝠生态、生理、和分子系统进化领域完成了大量研究，奠定了本项目组在此领域中的国际地位，首次在国际上证实性发现并系统研究了世界上第3种食鱼蝙蝠--大足鼠耳蝠；首次提出菊头蝠科蝙蝠回声定位叫声频率与耳长负相关；利用分子系统学研究方法澄清菊头蝠科内一些种的分类地位，菊头蝠科和蹄蝠科的关系，以及普通长翼蝠种群间的系统进化关系；系统地研究了扁颅蝠属仅有两个姐妹种的社会组织结构和生态位分化。

According to several types of Eco-dikes, several methods of revetment is brought forward, and several important problems in the process of building Eco-dikes is discussed and summarized; and the rivers rich in nature is concluded and compared, and it introduce the method of building river rich in nature in detail too.

The population dominance index, Shannon-Wiener index, evenness, niche breadth and community similarity were used to analyze the diversity and eco-niche of soil moniliaceous hyphomycetes in five ecosystem-types.

利用种群优势度、Shannon-Wiener多样性指数、均匀度、生态位宽度、群落相似性等指标对该地区不同生境的土壤淡色丝孢菌物种的生态多样性及物种生态位进行了分析。

It revealed: Firstly, the plant community, the major environmental factors illumination degrees, surface temperature, air temperature, day air humidity changes curve and changes in point of curve similar; Secondly, measuring three points mixed lawn-Chinese littleleaf box-Guohuai plant community in the three observation of the ecological effects of the plant community most obviously, its sunshade rates, the average surface temperature 0 cm Service rates, the average surface temperature -5.0 cm Service rates, the average temperature cooling rate, the average humidification effect respectively 36.3%, 34.7%, 18.9%, 6.9%, 13.9%; wood forest plant community occasions, mixed lawn-Chinese littleleaf box plant community smallest.

以校园为例进行实地观测，比较详尽地分析了生物种群组成的多样性对园林生态系统的影响，结果表明：①植物群落内的主要环境因子光照度、地表温度、空气温度、空气湿度的日变化曲线与对照点日变化曲线相似；②3种测点中混合草坪－黄杨－国槐植物群落在3种观测的植物群落中生态效应最明显，它的遮光率、地表0 cm处平均降温率、地表－5.0 cm处平均降温率、气温平均降温率、平均增湿效应分别为36.3%，34.7%，18.9%，6.9%，13.9%；桐树林植物群落次之，混合草坪－黄杨植物群落最小。

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。

However, it is difficult to accurately evaluate the water budget and water use efficiency of alpine meadow because ther imbalance was prevalent in this study site the sum of sensible and latent fluxes estimated by eddy covariance technique (EC method is often less than the difference between the net radiation and the soil heat flux.

本研究于2005年和2006年夏季的7～8月，利用小型蒸渗仪、波文比与涡度相关技术三种方法对青藏高原高寒草甸生态系统昼间的蒸散量进行对比研究，定量分析三种方法所得结果的差异，并试图分析其影响因子，为利用和正确评价涡度相关技术测定该生态系统的碳水收支提供了理论依据。
