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.
