地学基础（Learn basic） Environmental geology review materials 1. Characteristics of the environment: (1) integrity and regionality: the environment is a complete system composed of components and elements, and is called systematic. The components of the environment are linked in a certain way to form a certain structure, relatively stable material and energy flow network, thus enabling the environment to have a specific function. (2) variability and stability: the internal structure and external state of the environment are constantly changing under the combination of natural and human activities. Stability refers to the environment system has certain self-regulating function and characteristics. (3) resource and value; (4) public welfare. 2. Environment type: Settlement environment: (1) the crowd life place, is made up of some features different buildings and associated with the yard unit consisting of a basic environment, characteristic is more for artificial environment, is adjust measures to local conditions created by human. Limited capacity can be divided into village environment and urban environment. (2) geographical environment: the interplay, interpenetration, mutual restriction and intertransformation of the earths surface lithosphere, water circle, atmosphere, soil circle, biosphere, etc. From the top of the lithosphere to the bottom of the atmosphere, it provides a great deal of productive information for human activities - renewable natural resources. The settlement environment is created by human production labor on the basis of geographical environment. (3) geological environment: mainly refers to the hard crust or lithosphere coming down from the surface of the earth, which provides a large amount of production data for human production and development -- the unrenewable mineral resources. The geographical environment is based on the geological environment, and it develops and develops under the influence of cosmic factors. (4) the environment: refers to
