基于arcengine县域农用地适宜性评价系统分析word格式论文.docxVIP

用地适宜性评价的可视化、自动化和智能化。本研究系统主要是利用 ArcGISEngine 二次开发技术和 C#程序设计语言，针对系统的目标和需求，将整个系 统开发设计为用户操作管理、空间数据管理、属性数据管理、数据统计查询、 空间分析和农用地适宜性评价六个功能模块，整个系统基于图形用户界面的 设计思想，使系统结构合理、操作简便、界面友好、数据处理功能较完善， 对计算机的配置要求较低，具有较强的实用性和可移植性。最后，文本以广西隆安县为例，使用本系统对区域内农用地进行了适宜 性评价。选取地形坡度、排灌条件、土壤质地、≥10℃积温和石漠化程度等 7 个地理要素作为评价因子，通过系统功能模块的计算分析，得到最终的适宜 性评价成果。案例验证了评价方法与技术切实可行，以及系统可行性、可靠 性和有效性，同时，也为相关部门的科学规划管理提供良好的信息平台和科 学依据。关键词：农用地，适宜性评价，地理信息系统，ArcGIS EngineAbstractAgriculture is an important area of the current GIS application development. With the continuous development of geography and computer science, remote sensing, surveying and statistical theories and methods of introduction of geographic information systems theory, systems, methods and techniques on the great leap forward and the in-depth development and geographic information system in the field of agricultural applications has become more mature, a comprehensive and in-depth, continuously promote the development of agricultural modernization. Agricultural land suitability evaluation, is agricultural land management planning, promoting the Health Foundation for the development of agriculture. By suitability evaluation, can reach the quality and number of spatial distribution of agricultural land, but because of the various aspects involved in the evaluation of spatial data scale and evaluation technology also contains data such as image processing and numerical calculation. Therefore, agricultural land suitability evaluation system based on ArcEngine, not only to achieve effective integration of spatial data and attribute data and automated analysis, at the same time, reflect a more scientific and effective process of agricultural land suitability, so that the whole evaluation process efficient unified, meanwhile, provides information services and technical support for users.This research in the in-depth analysis of agricultural land suitability evaluation in domestic and foreign research status on the basis of, according to the characteristics and s
