生态种

In multidimensional space,the niche breadths of these plants tended to expand,whereas theniche overlaps tended to decrease and the niche separations tended toincrease.

Ecological infrastructure is the basic guarantee for regional ecosystem safety and the rigid bottom limit for regional environmental bearing capacity. For regional spatial planning, whose task is to arrange urban space, ecological space and agricultural space concordantly, and the purpose of SP is to create a harmonious relationship between nature and human and at the same time build a spatial order for eco-system sustainable development.

For regional spatial planning, which task is arrange urban space、ecology space and agriculture space concordantly, the purpose of SP is create a harmonious relationship between nature and human, at the same time, build a spatial order for eco-system sustainable developing.

摘 要：生态基础设施是区域生态安全的基本保障和区域环境承载的刚性底限，区域空间规划是对区域城市空间、生态空间及农业空间的统筹性安排，其目的是创造一种人地和谐、生态环境可持续的空间秩序。

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。

There is a background and process of the idea of circulative economies and the new model of the development will produce a great impact on the economic development of our country.

循环经济是一种新的经济形态，其本质上是一种生态经济，它要求遵循生态学规律，合理利用自然资源和环境容量，在物质不断循环利用的基础上发展经济，使经济系统和谐地纳人到自然生态系统的物质循环过程中，实现经济活动的生态化。

Objective To determine the niche breadth and overlap in eleven dominant species of gamasid mites parasitic on 39 species of small?mammal hosts around Biluoxueshan Mountain in Weixi, Yunnan.

目的 应用现代生态学中生态位的理论和方法，对云南省维西县碧罗雪山周边地带11种医学革螨在39种小兽宿主资源上的生态位宽度和生态位重叠进行研究。

In the face of the very grave environmental question and ecocides day by day, the mankind begins to realize that there should be involvement with regular law in the fields of people and natural relation, however, people"s ecological environmental awareness and concrete law are adjusted and only stayed on very undeveloped aspect, this kind of state reflects and protects in the criminal law of the ecological environment too, the legislative thoughts of most countries have inherited the value idea of the traditional criminal law, the traditional criminal law is regarded as the last kind of means to adjust social relationships, the target that adjust is interpersonal social relationships, the object protected by criminal law is that the people"s life , health and property are safe, it is a kind of idea of value taking human interests as the center that reflects.

面对日益深重的环境问题和生态危机，人类开始意识到在人与自然关系的领域中要有法律规则的介入，然而，人们的生态环境意识及具体的法律调整还停留在很不发达的层面上，这种状况反映在生态环境的刑法保护上更为明显，多数国家的立法思想继承了传统刑法的价值理念，传统刑法作为调整社会关系的最后一种手段，其调整的对象是人与人之间的社会关系，受刑法保护的客体是人的生命、健康和财产安全，体现的是一种以人类利益为中心的价值理念。

This paper concerns the analyses of niche breadths of and overlaps bet-ween several plant species in 3 Kobresia communities in the Haibei Research Station using the formula described by Levins and Pianka.

本文利用Levins和Pianka公式，在多维生态因子梯度上测定了海北地区高寒草甸三种嵩草群落中若干植物种的生态位宽度和生态位重叠。

The landscape eco-corridor for the disturbed area can be designed into five types, i.e. eco-corridor of shelter belt, eco-corridor of water front, eco-corridor of road, the eco-corridor for connecting the restored areas, eco-corridor of natural landscape.

将水利水电工程扰动区景观生态廊道设计为5种类型：防护林生态廊道、滨水岸线生态廊道、道路生态廊道、修复区连接廊道、自然景观生态廊道。

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