Research Of Generation And Application On The Green Map Of County

The ecological environment is the basis for human survival. Tang County is rich in mineral resources, will inevitably bring about the irrational use of resources and development driven by the interests, eventually leading to the ecological environment has been the deterioration and destruction. In order to better protect the environment, the production of green map to help people analyze the local ecological environment, Providing warn and basis in accordance with the already damaged state of the environment.Green Map is to use a globally GB clearly marked on the map to a variety of information together to form a reflection of a community cultural ecological landscape of the local comprehensive map. Green Map is not only to show the local "green" resources ,and we found that the characteristics and value of the residence, but also pushed the local ecological environment to disrupt the status quo image, comprehensive, intuitive unfolded, Causing people’s attention on the local ecological environment, and providing guidance to environmental protection, community planning in future.Green Map of Tang County is generated by Tang County range, In support of MapInfo, Photoshop, ArcGIS and other software, to generate a base map of the green image maps and land use map. To create a Green Map, First determine the theme of "Environment", and to determine the icon around the theme, and to collect data, and to determine the position shown, Green Map of Tang County is generated to make use of relevant software, it is that Can query or edit. It can be clearly seen the distribution and development of mineral resources and local ecological resources and features. on figure.To Green Map of Tang County, it analyze of the impact affect of Tang County iron ore and tailings to the surrounding environment. And analyze the value of ecosystem services of forest resources and reservoirs The results are as follows:1.Analyzing of iron ore dust pollution around has a great relationship with wind speed and direction, and mine tailings contaminated the surrounding water environment, air, land, and cause damage to vegetation area of 100 hectares, and the tailings can easily cause geological disasters.2. Evaluation Tang County forest ecological benefits can be drawn: the total value of forest ecological benefit to 29.78 billion yuan. Water conservation value of 1.4 billion yuan, the soils of forest conservation value of 210 million yuan, the benefits of carbon sequestration and oxygen release of 985 million yuan, the purification of atmospheric environment value of 310 million yuan, the value of biodiversity for 36.78 million yuan ,forest recreation value of 2.8 million yuan.3. Evaluation Tang County reservoir ecosystem services can be drawn: ecological function value of 12.96 billion yuan (cold and wet effect excluded), social function value of 8.298 million yuan.
