    摘要:

    耕地質量指標數據獲取是耕地質量評價的基礎,遙感為相關數據的快速,、大面積獲取提供了一種新的手段與方法,。本文首先分析了耕地質量內涵和功能,在此基礎上利用文獻計量法對我國近5年耕地質量評價指標研究進行歸納,,結合國外土壤質量的研究現狀,,提出了基于遙感技術的耕地質量評價指標體系,包括地形條件,、土壤屬性和田間利用狀況3個維度,。然后分析了不同維度各指標獲取方法的研究現狀,概述了目前常用的遙感數據分析方法及對應的技術原理,,遙感可有效獲取田面坡度,、田塊狀況、田間道路通達度,、林網化程度等指標計算所需的基礎數據,,土壤屬性的大尺度獲取方法還需進一步研究。最后針對遙感技術獲取耕地質量評價指標亟待解決的問題,,提出了建議與展望:挖掘耕地質量評價指標的不同尺度遙感特征,;加強耕地質量評價指標遙感信息的自動化提取研究,;建設耕地質量評價的遙感大數據平臺,促進遙感技術在耕地質量評價中的應用,。

    Abstract:

    The data acquisition of cultivated land quality index (CLQI) is the basis of cultivated land quality (CLQ) evaluation. Remote sensing (RS) provides a new method for rapid and large-scale monitoring of CLQ data. Firstly, the connotation and function of CLQ were analyzed. On this basis, bibliometric method was used to summarize the research of CLQI in recent five years. Combined with the research status of CLQ and soil quality, CLQI system was established based on RS, which was divided into three dimensions: topographic conditions, soil properties and field utilization status. Secondly, the research status of various index acquisition methods in different dimensions was analyzed, and the commonly used RS analysis methods and corresponding technical principles were summarized. The basic data can be effectively obtained for field slope, field condition, field road accessibility, forest network degree and other indicators, and the large-scale acquisition method of soil properties were needed further research. Finally, aiming at the problems to be solved in RS monitoring of CLQ, the following suggestions and prospects were put forward: mining the remote sensing characteristics of different scales of CLQI; strengthening the research on automatic extraction of remote sensing information of CLQI; and building a remote sensing big data platform for CLQ evaluation, so as to promote the application of RS in CLQ evaluation.
