基于限制因素和熱點(diǎn)分析的耕地整治質(zhì)量潛力測算
本文選題:耕地整治 切入點(diǎn):質(zhì)量潛力 出處:《農(nóng)業(yè)機(jī)械學(xué)報(bào)》2017年02期
【摘要】:以規(guī)則網(wǎng)格為評(píng)價(jià)單元,采用因素組合法對(duì)耕地自然質(zhì)量限制因素進(jìn)行分析;采用熱點(diǎn)分析法對(duì)耕地利用水平指標(biāo)進(jìn)行局部聚類;并分別測算限制因素改變和利用水平指標(biāo)提升后的耕地質(zhì)量變化。以河北省涿州市為研究區(qū)進(jìn)行研究,結(jié)果表明:灌溉保證率是涿州市耕地自然質(zhì)量的限制因素,經(jīng)改善灌溉條件的耕地自然等指數(shù)可平均提升408。涿州市耕地整體利用水平相差較大,可依據(jù)熱點(diǎn)分析結(jié)果提出相應(yīng)的耕地平整、修建溝渠或田間道路等工程措施,改善土地利用條件,提高耕地利用等指數(shù)。綜合整治潛力呈現(xiàn)東西低、中部高的分布特點(diǎn)。所提出的耕地整治質(zhì)量潛力測算方法有助于確定耕地質(zhì)量限制因素、劃分耕地整治區(qū)域及指明整治方向。
[Abstract]:Taking regular grid as the evaluation unit, the factor combination method is used to analyze the factors limiting the natural quality of cultivated land, and the hot spot analysis method is used to cluster the cultivated land utilization level index locally. The results show that irrigation guarantee rate is the limiting factor of the natural quality of cultivated land in Zhuozhou City, Hebei Province, and the change of cultivated land quality after the change of limiting factors and the improvement of utilization level index are calculated separately, the results show that irrigation guarantee rate is the limiting factor of natural quality of cultivated land in Zhuozhou City. The natural index of cultivated land after improving irrigation conditions can be increased by 408.The overall utilization level of cultivated land in Zhuozhou is quite different, and corresponding engineering measures, such as leveling cultivated land, constructing ditches or field roads, can be put forward according to the results of hot spot analysis. Improvement of land use conditions, improvement of cultivated land use index and so on. Comprehensive remediation potential is characterized by low distribution in east and west and high in central part. The method of measuring cultivated land quality potential is helpful to determine the limiting factors of cultivated land quality. Divide cultivated land regulation area and point out regulation direction.
