The indicator system of ecological security of agricultural sustainable development in the Tongyu County was established,the weight of the indicator was determined by the method of mean square deviation,ecological security of agricultural development of 1985,1990,1995,1998,2001 and 2004 were evaluated by the model of ecological security.

建立了通榆县农业可持续发展的生态安全评价指标体系，采用均方差法确定了评价指标的权重，对研究区1985、1990、1995、1998、2001、2004年6个时段的农业生态安全进行了评价。

As a case study of Tongyu county,Jilin Province,This paper established the indicator system of ecological security on agricultural sustainable development,determined the weight of the indicator by the method of mean square deviation,and evaluated ecological security on agricultural development among 1985, 1990,1995,1998,2001 and 2004 by using the model of ecological security.

以吉林省通榆县为例，构建了县域农业可持续发展的生态安全评价指标体系，采用均方差法确定了评价指标的权重，对研究区1985、1990、1995、1998、2001、2004年6个时段的农业生态安全进行了评价。

None but adopt rational measures and vigorously enhance the management of entironment in study area; only in this way can we meliorate the health status of ecosysytem.

Improve ecological garden from the psychological and mental state of deficiency in human services, the overall goal is to pursue coordination with the environment, essentially a man-made main ecological problems.

生态园林从改善人的心理机能和精神状态上服务于人类，总的目标就是追求人与环境的协调，实质上是一个以人为主体的生态问题。

Results show that phanerophytes is the dominant life form in the three forests, in which micro-phanerophytes is in the largest proportion, and then followed by hemicryptophytes. In the three communities, the principal leaf size is mesophyl1, the main light eco-form is heliophyle, and the dominating water eco-form is mesophyte.

结果发现，3个群落都以高位芽植物为主，其次为地面芽植物；在高位芽植物中又都以小高位芽植物比例较高；3个群落的叶型谱以小型叶为主，光照生态类型谱以阳生种类为主，水分生态类型谱以中生种类占优势。

"Ecosystem" means a dynamic complex of plant, animal and micro-organism communities and their non-living environment interacting as a functional unit.

"生态系统"是指植物、动物和微生物群落和它们的无生命环境作为一个生态单位交互作用形成的一个动态复合体。

No intestinal microflora dysfunction was found in control patients.

Difference target leads to difference decision element. The decision element of the state include ecology and poverty, the decision element of region government include achievement, system or policy, and money, the decision element for migrator include personality, distance, infrastructure, culture and migratory cost.

不同的目标导致决策因素的不同，认为生态和缓贫是国家生态移民决策的主要因素；认为政绩、制度、资金因素是地方政府决策的主要因素；个体、迁移距离、迁入地基础设施、社区文化、迁移者的成本效益是影响迁移者决策的主要因素，并以此构建国家、地方政府和迁移个人的决策模型。

Soil nitrogen mineralization in forest ecosystems is one of the most important indicators for normal ecosystem functions.

Two-dimensional scatter plot of principal axes analysis,systematic cluster tree and the minimal spanning tree on the basis of niche overlaps were drawn,which revealed the ecological similarity of 42 moss species.The combinative application of principal axes analysis,systematic cluster analysis and minimal spanning tree method on the basis of niche overlaps could express the ecological similarities among species intuitively.

以此为指标，分别应用主坐标排序、图论聚类及系统聚类分析方法，作出了反映42种地面藓类的种间生态关系的二维投影图、最小生成树和动态聚类图。3种方法相结合，能够对生态位重叠值矩阵进行直观地表达，并使所表达的藓类种间关系具有确切的生态学含义。

The split between the two groups can hardly be papered over.
