摘要On the basis of field investigation and data collection, ecological function principles, together with qualitative and quantitative methods are applied in this paper to analyze eco-environment situation and reveal space differentiation rules of eco-environment sensitivity and ecosystem services importance of Karamay City middle area. Consequently, combined with the developing characteristics of its own society and economy, according to the division principle, basis and methods, Karamay City middle area can be divided into 3 ecological function regions and 39 ecological function small regions. Meanwhile, according to the eco-environment characteristics, main eco-environment problems and ecological functions of each ecological function regions, key tasks and specific measures on ecological nursing and construction are put forward to provide a scientific basis for ecological construction planning in the middle area of Karamay. The main conclusions of this paper are listed as follows:(1) The eco-environment is fragile, and regional eco-environment question is outstanding in the middle area of Karamay. Lack of precipitation, water resources are deficient. The type of vegetation and ecosystem are single, the forest resources are increased, but the coverage is still low, and the vegetation is destroyed seriously. The soil erosion in the mountain area is significant, the trend of land desertification in the plain is obvious, and the soil salinization is serious. (2) From the spatial distribution characteristics of eco-environment sensitivity of Karamay middle area, highly sensitive and extremely sensitive are mainly distributed. Spatial differentiation is obvious, we should adjust measures to local conditionsa and make reasonable moderate development in development process. Eco-environment extremely sensitive regions are mainly distributed in the northern of Shixi Road, the southern of Industrial Park, Wu Ming Hu wetland, the middle area of West mountain. (3) From the spatial distribution characteristics of ecosystem service function of Karamay middle area, important and extremely important are mainly distributed. Space differentiation is obvious, we should focus on management development and construction in view of the dominant ecological function. Extremely important regions are mainly distributed in the north of Kuibei Railway, part of the region between Shixi road - Kuibei Railway, Wu Ming Hu wetland, Mahe old river of Xiaoguai-Zhongguai, southern part area of Industrial Park. (4) GIS technology through the spatial overlay is applied in this paper to divide Karamay middle area into 3 ecological function regions and 39 ecological function small regions. Eco-environment sensitivity, ecosystem services and the already existing problems and causes in each ecological function region are analyzed. The ecological construction measures and development directions of 39 ecological function regions are put forward at last.
其他摘要本论文在现地调查和资料收集分析的基础上,运用现代生态学区划理论,采用定性与定量相结合的方法,揭示克拉玛依市中部区域荒漠生态环境现状、生态环境敏感性及生态服务功能空间分异规律;然后结合研究区的特点,按照一定的区划原则、依据和方法,对克拉玛依市中部区域荒漠进行生态功能区划分,同时根据各功能区的生态环境特点、主要的生态环境问题和主导生态服务功能,提出各区生态保育与建设的重点任务和具体措施,旨在为克拉玛依市荒漠生态建设规划的实施提供科学依据和技术支撑。 (1)克拉玛依市中部区域荒漠生态环境脆弱,区域性生态环境问题突出。降水稀少,水资源匮乏。植被类型和生态系统类型比较单一,森林资源虽有增加,但覆盖度仍较低,且植被破坏严重。山区及山前倾斜平原区土壤侵蚀显著,平原区土地沙漠化趋势明显,土壤盐渍化严重。(2)克拉玛依市中部区域荒漠生态环境敏感性空间分布特征表明,生态环境敏感性以高度敏感和极敏感分布为主,空间分异明显,开发过程中应因地制宜,合理适度开发。极敏感区主要分布在石西公路以北的广大区域,工业园区南部,无名湖湿地区域以及西部加依尔山山前地带中间小部分区域。(3)克拉玛依市中部区域荒漠生态系统服务功能空间分布特征表明,生态系统服务功能以重要和极重要分布为主,空间分异明显,针对各区的主导生态功能,重点治理开发与建设。极重要区主要分布在奎北铁路以北的广大区域,石西公路-奎北铁路之间的部分区域,无名湖湿地,小拐-中拐玛河古道区域,工业园区南部部分区域。(4)运用GIS技术,通过空间图形叠加,将克拉玛依市中部区域荒漠划分为 3 个生态功能区, 39个生态功能小区,并分析各功能区存在的生态环境问题及成因、生态环境敏感性、主要的生态系统服务功能,提出了各功能区的生态建设对策和方向。
