基于云平台的生态承载力评价系统设计与实现
发布时间：2018-07-25 09:02
【摘要】：近些年,随着互联网的发展和用户需求的转变,GIS技术也在此基础上得到进一步提升,传统单一的基础数据处理与分析功能已经不能满足专业应用的需求,面向对象的和具体功能的技术集成的应用需求增大。伴随着神农架林区城市化和工业化的推进,生态环境问题更加突出,而其自身特殊的生态地位对其自身的生态环境提出更加严格的要求,二者之间的矛盾日益凸显,对神农架林区生态承载力的评价迫在眉睫。在过去的几十年里,林区城镇化道路不明确,缺乏自主创新的城市规划和管理的核心技术,因此,设计一套面向对象的、基于云平台服务的数据处理与服务功能的生态承载力评价系统具有重要现实意义。本文基于对生态承载力概念与评价方法等理论体系研究的基础上,确定生态承载力评价系统的各大功能模块,基于云平台设计开发生态承载力评价系统,实现对神农架林区生态承载力的评价,指导整个林区的生态保护建设与综合对策的制定。在对整个林区进行生态承载力评价的基础上,再通过人与生态耦合关系理论,采用离差系数,分析生态与人口、生态与经济、生态与社会的发展协调度,以林区镇域为评价单元,阐述生态发展的影响因素,并给出保护对策。评价分析的主要结论如下:(1)对整个林区的生态承载力评价,结果显示林区整体呈现出适载状态,整个林区的生态承载力还能继续维持区内生态系统的正常功能,但仍有较大改善空间。空间分布上,林区生态承载力分布不均匀;数量上,林区生态敏感区占全区总面积的49%。基于林区整体的生态承载力评价结果,可以发现林区生态承载力面临着旅游业的繁荣给生态环境造成巨大压力、神农架林区特殊的自然基质条件、对资源的不合理开发利用、生态保护政策的缺失等多方面问题,并以此从生态系统外部角度给出具体综合对策。(2)以生态系统与其内部结构的耦合关系评价为方法依据,详细阐述神农架林区生态与人口、社会、经济的耦合关系特征,从整体来看,神农架林区人口-生态协调性整体水平较低,大部分镇的人口-生态协调度水平处于中高失调等级;林区经济-生态协调性整体水平较低,大部分地区经济-生态协调度水平处于中高度失调等级;林区经济-生态协调性整体水平较低,大部分地区经济-生态协调度水平处于中高度失调等级,据此分析,对林区各镇给出具体对策和发展建议。
[Abstract]:In recent years, with the development of the Internet and the change of user demand, GIS technology has been further improved, the traditional single basic data processing and analysis function can no longer meet the needs of professional applications. Application requirements for object-oriented and functional-specific technology integration are increased. With the promotion of urbanization and industrialization in Shennongjia forest area, the ecological environment problem is more prominent, and its own special ecological status puts forward more stringent requirements for its own ecological environment, and the contradiction between the two becomes increasingly prominent. It is urgent to evaluate the ecological carrying capacity of Shennongjia forest area. In the past few decades, the path of urbanization in forest areas has been unclear, and the core technologies of independent and innovative urban planning and management have been lacking. Therefore, the design of a set of object-oriented, The evaluation system of ecological carrying capacity based on cloud platform service data processing and service function has important practical significance. Based on the study of the concept and evaluation method of ecological carrying capacity, this paper determines the functional modules of the ecological carrying capacity evaluation system, and designs and develops the ecological carrying capacity evaluation system based on cloud platform. The ecological carrying capacity of Shennongjia forest area is evaluated to guide the ecological protection construction and the formulation of comprehensive countermeasures. On the basis of the evaluation of ecological carrying capacity of the whole forest area, and through the theory of human-ecological coupling relationship and the coefficient of deviation, this paper analyzes the degree of coordination between ecology and population, ecology and economy, ecology and society. Taking the forest area as the evaluation unit, this paper expounds the influencing factors of ecological development and puts forward the protection countermeasures. The main conclusions of the evaluation and analysis are as follows: (1) the ecological carrying capacity of the whole forest region is evaluated. The results show that the ecological carrying capacity of the whole forest region is in a suitable state, and the ecological carrying capacity of the whole forest region can continue to maintain the normal function of the ecosystem in the whole forest region. But there is still much room for improvement. In spatial distribution, the ecological carrying capacity of forest region is not uniform, and the ecological sensitive area of forest region accounts for 49% of the total area of the whole area. Based on the evaluation results of ecological carrying capacity of forest region as a whole, it can be found that the ecological carrying capacity of forest region is facing great pressure to the ecological environment caused by the prosperity of tourism, the special natural matrix condition of Shennongjia forest area, and the unreasonable exploitation and utilization of resources. The lack of ecological protection policy and so on are discussed in detail. (2) based on the evaluation of the coupling relationship between ecosystem and its internal structure, the ecological and population of Shennongjia forest region are expounded in detail. On the whole, the overall level of population-ecological coordination in Shennongjia forest area is low, and the level of population-ecological coordination degree of most towns is in the middle and high level of maladjustment. The overall level of economic and ecological coordination in forest regions is low, the level of economic and ecological coordination in most areas is in the middle and high degree of imbalance, and the overall level of economic and ecological coordination in forest regions is relatively low. The level of economic-ecological coordination in most areas is in the middle and high degree of maladjustment. Based on this analysis, concrete countermeasures and development suggestions are given for each town in the forest area.
