生物多样性

To keep certain number of greater patches through protection and restoration in urban area is meaningful;(2) small greenland patches with diverse structure may promote the heterogeneity of urban landscape, and serve as colonial land and stepping stones for certain populations, and create rich types of habitats and ecological niches. So laying small patches in urban environment is also important. Incorporation of the coarse grain and fine grain, aggregation and outliner of landscape elements may creates better landscape patterns;(3) many literatures have showed that good landscape connectivity benefits the longer persistence of species and the conservation of biodiversity.

大的绿地斑块有多种作用，通过城市地区自然景观斑块的保护或城市绿地的建设，在城市中维持一定的较大规模的绿地斑块是有积极意义的；（2）结构不同的小的绿地斑块可增加城市的景观异质性，为生物提供迁徙地、扩散暂歇地，创造丰富的生境资源和生态位，因此，结合大的绿地斑块的建设，同时布置小的绿地斑块作为补充，粗粒、细粒结合，集聚、分散结合是形成优良绿地景观格局的途径；（3）诸多的文献已显示，好的景观连接性有利于物种持续较长的时间，从而有利于生物多样性的保护。

Some of the regional changes analyzed are Baltimore-Washington urbanization, Great Lakes landscape change, Upper Mississippi River vegetation, Greater Yellowstone biodiversity, Southwestern US paleoecology, Palouse bioregion land use history, Northeastern forest dynamics, and land use history of the Colorado Plateau.

分析了一些区域变化，如：Baltimore-华盛顿城市化、大湖区景观变化、密西西比河上游植被、大黄石地区的生物多样性、美国西南地区古生态学、Palouse生物区土地利用历史、东北地区森林动力学、以及科罗拉多高原的土地利用历史。

The effects of building a water conservancy project include soil submerging, transmigrant, public health, micro-climate, soil salinization, environmental and geological disaster, deposition and alluviation, changing of ecological environment, wetland, biodiversity and environmental influence during the construction period of project, etc.

这些影响包括淹没土地、移民、人群健康影响、小气候影响、土壤的沼泽化和盐碱化问题、环境地质和自然灾害问题、上淤下切、生物环境的变化、湿地影响、生物多样性影响以及施工过程对环境的影响等。

The floristic equilibrium point and its biogeographic significance are important for understanding the floristic origin, distribution, and spatial patterns of plant diversity.

了解植物区系平衡点及其生物地理意义对于理解植物区系的起源、分化以及生物多样性空间格局的形成等方面均具有重要意义。

Three indigenous latifoliate species namely Castanopsis fissa,Elaeocarpus sylvestris and Schefflera octophylla were selected from the forest for the purpose of water conservation in the scope of midst and small reservoirs in Shantou to determine the species diversity,natural regeneration and stability of communities.

生物多样性是生物及其与环境形成的生态复合体以及与此相关的各种生态过程的总和，包括数以百万计的动物、植物、微生物和它们所拥有的基因以及它们与其生态环境形成的复杂生态系统，是生命系统的基本特征[1]。

So that, consummating our country's Legal system of ecological security is more important for our biodiversity conservation and ecological security's protection.

因此，完善我国的生物安全的法律制度，对于我国的生物多样性保护和生态安全的保护极为重要。

For example, because the people to pollute compared to the volume biology which borders on exterminates even more take seriously, biodiversity involves about environmental pollution's law and the rules and regulations to more be stricter.

例如，由于人们对污染比对濒临灭绝的额生物更加重视，关于环境污染的法律和规章比涉及生物多样性的要更多更严格。

Urban ecological park will improve urban greenland landscape, health and stability, form the key areas for biodiversity and natural conservation, supply the demand to get in touch with nature for residents through ecological approaches, such as naturalizing park, developing the natural potential, restoring and rehabilitating plant communities with potential vegetation characteristics and introducing wildlife into park.

生态公园是以生态途径改善城市绿地景观，促进公园绿地生境的自然化和多样化，诱导城市绿地的自然潜力，恢复和重建潜在植被特征的群落，提高绿地的健康水平和稳定性，为野生生物提供和改善生存空间，形成城市生物多样性保育和自然保护的关键地，满足市民接触大自然的需求。

Be directlyused as materials of architecture, art crafts, paper, charcoal, vegetables,medicine and so on. They can also be used as horticulture plants in gardens. They even promote the ecological function of water and soil conservation, weather regulation, air cleaning, noise reduction and wild life protection.

竹类植物具有作为建筑材料、工艺品原料、造纸原料、竹炭原料、竹笋食品及制药原料等直接使用价值，并具有作为园林观赏对象的间接使用价值，还具有水土保持、调节气候、净化空气、减少噪声及维护竹林野生生物的生物多样性等生态服务功能。
