摘要:

耕地质量作为反映耕地不同性状的综合性指标,对农业可持续发展有重要意义,文章综述了高分辨率遥感数据在耕地质量评价中的应用情况。当前耕地质量评价信息采集技术中存在监测范围小、监测时间跨度短、成本高、效率较低等问题,难以实现耕地质量的快速、准确评价。高空间分辨率、高时间分辨率、高光谱分辨率的遥感影像为长时序、大范围的耕地质量评价提供了技术支撑和数据基础。文章总结了国内外应用高分辨率遥感数据对地形特征、田间基础设施、生物多样性、土壤性状、农田环境状况等指标识别方法。文章在介绍耕地质量等级评价方法基础上,归纳了植被指数协同评价法,结合主成分分析法提出了基于高分辨率遥感的耕地质量评价方法,探索基于高分辨率遥感的耕地质量评价指标获取方法和评价体系,以期为快速、准确耕地质量评价研究提供参考。

Abstract:

As a comprehensive index reflecting different characteristics of cultivated land, the quality of cultivated land is of great significance to the sustainable development of agriculture. This paper summarizes the application of high resolution remote sensing image in the evaluation of cultivated land quality. At present, there are some problems in the information collection technology of cultivated land quality evaluation, such as small monitoring range, short monitoring time span, high cost, low efficiency and so on. Remote sensing images with high spatial resolution, high temporal resolution and high spectral resolution could provide technical support and data basis for long-term and large-scale cultivated land quality evaluation. This paper summarizes the application of remote sensing technology to identifying terrain features, field infrastructure, soil properties, farmland environment and biodiversity and other cultivated land quality evaluation indicators at home and abroad. Based on the introduction of cultivated land quality grade evaluation method, the vegetation index collaborative evaluation method is summarized. To provide reference for rapid and accurate evaluation of cultivated land quality, on the basis of introducing the evaluation method of cultivated land quality grade, this paper concludes the cooperative evaluation method of vegetation index, at the same time, the evaluation method of cultivated land quality based on high resolution remote sensing is proposed combined with principal component analysis. This paper explores the acquisition method and evaluation system of cultivated land quality evaluation index based on high resolution remote sensing.
