    摘要:

    耕地質(zhì)量指標(biāo)數(shù)據(jù)獲取是耕地質(zhì)量評價的基礎(chǔ),遙感為相關(guān)數(shù)據(jù)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(zhì)量內(nèi)涵和功能,在此基礎(chǔ)上利用文獻(xiàn)計量法對我國近5年耕地質(zhì)量評價指標(biāo)研究進行歸納,,結(jié)合國外土壤質(zhì)量的研究現(xiàn)狀,,提出了基于遙感技術(shù)的耕地質(zhì)量評價指標(biāo)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(biāo)獲取方法的研究現(xiàn)狀,,概述了目前常用的遙感數(shù)據(jù)分析方法及對應(yīng)的技術(shù)原理,遙感可有效獲取田面坡度,、田塊狀況,、田間道路通達(dá)度、林網(wǎng)化程度等指標(biāo)計算所需的基礎(chǔ)數(shù)據(jù),,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(shù)獲取耕地質(zhì)量評價指標(biāo)亟待解決的問題,提出了建議與展望:挖掘耕地質(zhì)量評價指標(biāo)的不同尺度遙感特征,;加強耕地質(zhì)量評價指標(biāo)遙感信息的自動化提取研究,;建設(shè)耕地質(zhì)量評價的遙感大數(shù)據(jù)平臺,促進遙感技術(shù)在耕地質(zhì)量評價中的應(yīng)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.
