【摘要】 土地利用现状调查是我国法定的一项重要制度,它影响着国民经济和社会的发展,涉及每一个土地权利人的土地权益,也是一项技术性和政策性都较强的工作。对于土地利用现状调查数据来说,数据的生命力在于它的准确性、真实性和数据更新的现势性。在农村土地利用现状调查中,查清全国耕地、园地、草地、林地、农村居民点等各类土地的分布和利用现状是一项非常庞大的工作,需要大量人力物力的投入。因此,快速有效地获取地类调查数据显得尤为重要。在陕西省第二次农村土地利用现状调查中,地类调查方法为全野外调绘和综合调绘法。经过资料的收集、分析和整理,发现这两种方法均有许多缺点。基于此,本文提出了一种在综合调绘基础上改进的调查方法——“3S综合调绘法”。“3S综合调绘法”是利用GPS定位,通过野外实地踏勘确定各地类解译标志以及分类地类类型,在此基础上,对遥感图像分类并进行一些分类后处理,然后进行栅格到矢量数据的转换,再利用ArcGIS中的相关模块对矢量数据进行平滑以及抽稀处理,得到基础地类图斑数据。本文选取陕北甘泉、关中合阳和陕南宁强的部分区域作为试验区,阐述了“3S综合调绘法”的具体数据处理流程并进行了精度分析。实验发现：此方法具备一定的可行性；同时,确定了处理过程中的最佳参数范围。更多还原

【Abstract】 Land use survey is an important legal system of China, which affects the development of national economy and society. It not only involves each person’s land rights, but also has a strong technology and policy. The vitality of land survey data is the accuracy, authenticity and the timeliness.In Rural land use survey, identifying the land distribution and status of land using of the national cultivated land, grassland, forest, rural residential and other types is a very large task which requires considerable human and material resources. Therefore, fast and efficient access to land type of investigation data is particularly important.This paper is written by combining with the second rural land survey of Shaanxi Province. In this project, the commonly used methods to survey the land type are two ways. one is the whole field survey, the other is the comprehensive survey. Based on data collection, analysis and sorting, it found that both methods have many shortcomings. This paper proposes an improved method base on comprehensive survey-"3S comprehensive survey".3S comprehensive survey:after the field survey and investigation Using GPS positioning, determine the interpretation signs and the type be classified.On this basis, first, classify the remote sensing image of test area and do some post-processing. Secondly, convert the raster data to vector data and smooth and simplify the data with related ArcGIS modules. And then obtain the foundation land class polygon data.This paper described Specific data processing and did accuracy analysis by test area in Ganquan, Heyang and Ningqiang County. Experiments show that the method has a certain degree of feasibility and determine the optimum range of parameters in the data processing.更多还原
