摘    要:土地利用转型包含显性形态和隐性形态的变化,而土地利用强度是土地利用隐性形态的重要指征,既可以反映出人类对土地的干预程度,又可以呈现出特定时期社会经济发展状态。本文以土地利用强度的定量测度为抓手,基于分县统计数据及遥感解译的土地利用数据计算了区域土地利用隐性形态的变化,探讨了区域土地利用转型与粮食产量的耦合关系。研究表明:(1)1990—2010年,黄淮海地区耕地利用强度不断增加,而村庄建设用地利用强度快速减少,且区域时空格局差异明显;(2)耕地利用强度-村庄建设用地利用强度-粮食产量耦合类型时空演化特征明显,"低-低-低"类型主要分布在环渤海湾地区,而"高-高-高"类型主要集聚于冀鲁豫交界地区;(3)土地利用转型推动粮食生产格局不断演化,二者耦合关系模式将呈现出由"拮抗"到"协调"的转化过程。综上所述,土地利用转型过程中,科学优化土地利用转型与粮食生产的耦合关系,对保障区域粮食安全有重要作用。

关 键 词:黄淮海地区  土地利用转型  隐性形态  粮食生产转型  耦合关系

Abstract:Land use transition is a mirror of socio-economic development with the changes of both dominant and recessive land use morphologies. Especially, land use intensity is an important attrition of recessive land use morphology, which presents human intervention toward land and regional socio-economic development. Based on the quantitative measure of land use intensity of farmland and rural construction land, this paper described the changes of recessive land use morphology. Furthermore, the coupling relationship between land use transitions and grain yield(GY)was established. The results showed:(1)From 1990 to 2010, the pattern of land use intensity showed prominently difference in Huang-Huai-Hai Plain, with farmland intensity (LUIF)increased while rural construction land intensity(LUIR) decreased;(2)The spatio-temporal patterns of the coupling types of LUIF, LUIR and GY changed obviously, in which the coupling types of"low-low-low"mainly distributed in the Bohai Bay region, and the coupling types of"high-high-high"concentrated in border area of Hebei, Shangdong and Henan provinces; and (3)Land use transitions promoted the evolution of grain production with a coupling relationship from antagonism to coordination between two of them. During the process of land use transitions, in conclusion, it is greatly useful for regional food security by scientific optimizing the coupling relationship between land use transitions and grain yield.
Keywords:Huang-Huai-Hai Plain  land use transitions  recessive morphology  transition of grain production  coupling relationship
