中文摘要在点源污染逐渐得到控制后,非点源污染对环境的影响就开始显现出来,并且成为损害水质的重要源头。由于非点源污染源的复杂性、不确定性和污染影响范围的广阔性,使得人们不可能在野外对所有非点源污染进行监测。因此,GIS技术的引入,使得小流域农业非点源污染模拟、管理进入了信息化、数字化时代。GIS技术就成为小流域农业非点源污染模拟、管理和综合分析的强有力工具。 在“中国科学院西部行动计划——三峡库区水土流失与面源污染控制试验示范”项目资助下,从面源污染的科学体系出发,在组件式GIS(ComGIS)的研究基础上,针对三峡库区农业非点源污染研究的需要,探索了一条在面向对象程序设计语言Visual Basic 6.0环境下以ArcGIS二次开发平台ArcEngine开发小流域农业非点源污染机理模型的道路。 本文首先综述了小流域农业非点源污染模型,介绍了地理信息系统发展及其在小流域农业非点源污染研究中的应用。然后对小流域农业非点源污染机理模型进行了深入系统的剖析。详细介绍了ArcEngine组件开发方式,并在面向对象开发平台Visual Basic 6.0上进行了小流域农业非点源污染机理模型的开发。实现了水文分析、表面分析、坡长提取、插值计算、矢量栅格转换、栅格计算及空间要素查询等GIS基本功能,并实现了小流域地表径流、水土流失、氮磷等污染物负荷的快速、高效模拟,且以图形形式输出模拟结果。 本文以重庆市忠县申家河小流域为例,展示了小流域农业非点源污染机理模型在三峡库区农业非点源污染模拟中的应用效果。从模拟的结果发现,开发的小流域农业非点源污染机理模型对三峡库区小流域具有一般适用性,其它小流域农业非点源污染模拟也与之类似,因此可以推广到其它地区。 本文基于对小流域农业非点源污染机理模型的剖析,在前人理论研究成果的基础上,开发了小流域农业非点源污染机理模型。小流域农业非点源污染机理模型的开发是将最新的科技成果运用到小流域农业非点源污染的研究、规划、管理中,提高小流域农业非点源污染的信息化和自动化水平,为政府及相关部门的管理决策提供有效的支持,对全国其它地方类似模型的开发都具有重要的意义。
英文摘要Since 1970', the influence of the non-point source (NPS) pollution to the environment has been revealed, and become the main source of damaging the water quality. Because of the uncertainty and extensity, it is impossible to inspect all the non-point source pollution in the field. So the introduction of GIS technology has already made the management of agricultural non-point source pollution enter the information and digitization era.The GIS also has become the comprehensive strong tool for the estimation,management and general analysis of agricultural non-point source pollution. Funded by the "Plan of Action for the western Chinese Academy of Sciences —the Three Gorges reservoir area soil and water conservation and agricultural non-point source pollution Demonstration Area" project, starting from the scientific system of agricultural non-point source pollution, taken SHENJIA River watershed as an example, based on the theory of ComGIS technology, agricultural non-point source pollution mathematical modeling development and its application are discussed in this paper. First of all, agricultural non-point source pollution mathematical modeling is summarized and then geographic information systems development, researchs in the application of agricultural non-point source pollution, and agricultural non-point source pollution model are introduced. The development methods of the ArcEngine components is described in this paper, and agricultural non-point source pollution mathematical modeling is developed on the object-oriented development platform VISUAL BASIC 6.0.The developed agricultural non-point source pollution mathematical modeling realized hydrological analysis, surface analysis, slope length extraction, interpolation calculation, conversion between Vector and raster , enquiry of space elements and other functions, such as estimation of the land surface runoff, soil erosion and N/P pollution loading.The estimated results are exported through raster graphics. Taking SHENJIA River Valley in Zhongxian County as an example, the application effect of the agricultural non-point source pollution in the Three Gorges rapid land surface runoff, soil erosion and N/P pollution loading estimation is displayed. It also can be applicability on the other small watershed in Valley of the Three Gorges. The agricultural non-point source pollution mathematical modeling with similar functions, and it can be extended to other areas. Based on the analysis of process of agricultural non-point source pollution mathematical modeling in small watershed and the outcome of the previous theoretical study, the develepment of the small watershed agricultural non-point source pollution mathematical modeling provids a scientific basis for the latter development of agricultural non-point source pollution. Development of agricultural non-point source pollution mathematical modeling based on ArcEngine is explored and development and improvement of small watershed agricultural non-point source pollution study is promoted further in this paper.
