土地利用

Being one of environment sensitivity elements, land use occupancies consequence of environment study in monitor and sustainable development.

土地利用作为生态环境系统的一个敏感因子，因其受自然地理因素和人类社会活动的双重影响，在生态环境监测和可持续发展研究中占有非常重要的地位，因此，土地资源问题研究是当今资源与环境问题研究的核心内容之一。

There is a complicated no-linear relation of dynamic coupling between regional land use and eco-environment by the common interface of land ecology system, which can be regarded as a composite system with vivid dissipation structure characteristics. The composite system has a balance mechanism of entropy, and evolves in logistic curve.

区域土地利用与生态环境之间存在复杂的、非线性、动态耦合关系，这种耦合关系可以看作是二者以土地自然生态系统为公共界面耦合而成的具有鲜明耗散结构特征的复合系统，其内部存在明显的熵值平衡机制，演化轨迹也呈V型。

Investigation and evaluation of soil and water resources in Minqin Oasis indicate that the proportion of grain crop, cash crop and grass is 36.94:45.16:17.90 for 2005. And a comparison with that for 1991 indicates that land use structure is developing towards rational proportion of grain crop, cash crop and grass; and harmony among agriculture, stockbreeding and forest. The main limiting factors of land resources are water, soil quality, salinity and fertility, and there is about 3.9218×10^8 m^3 water deficit per year in Minqin Oasis.

通过水土资源现状的分析评价，发现2005年民勤绿洲粮经草比例为36.94：45.16：17.90，与1991年相比，土地利用格局正向粮经草比例优化和农林牧协调方向发展；民勤绿洲土地资源的限制性因素主要为水分、土质、盐碱和肥力；对水资源现状分析发现民勤绿洲年缺水量达3.9218亿立方公尺。

Land-use/land-cover change and carbon cycle form two of the most substantial aspects of global climate change on both global and regional scales.

土地利用／土地覆盖变化和碳循环问题是与当今人类生存和发展休戚相关的全球气候变化研究中的热点问题。

The term is generally applied to catchments smaller than river basins where there is a close relation between land use and water resources and the management of land and water mainly is a local issue.

该术语通常用于较小的流域，在这里土地利用与水资源之间有密切的关系，土地和水的管理主要是局部性问题。

The results indicate that the land use benefits are the most important driving force of land conversion.

研究结果：土地利用收益的不同是土地用途转化的最直接驱动因素；新增建设用地仍然是拉动和促进国家及地方经济发展的主要动力；提出了应用税收等经济手段平衡农业用地与建设用地的措施对策。

No matter in the whole world, country or yardstick of area, land use change always lead to land cover change .

无论是在全球还是国家或区域的尺度上，土地利用的变化总是不断地导致土地覆盖的变化。

Land Use is a economic active process that human get material products and service with land as subject of labor to satisfy themselves needs.

土地利用是人类以土地为劳动对象，获得物质产品和服务，以满足自身需要的经济活动过程。
