    摘要:

    以河南省境内分属于4个水文流域的县域行政单位为研究对象,从县域耕地和县域人均耕地两个视角探索4个流域在不同研究时期耕地规模、耕地非农化数量、耕地非农化率,以及耕地非农化对粮食生产的影响。研究表明:(1)河南省境内的4个流域的耕地规模及其空间分布均与流域内的土地面积和地形地貌有关。各流域内部县域耕地面积增减的态势和空间格局不尽相同。(2)在研究前期(1994-1999年),全省大部分县域耕地面积变化率为负,且区间分布集中,而在研究后期(1999-2004年),全省大部分县域耕地面积变化率为正,且区间分布分散。(3) 4个流域的人均耕地面积均减少,在不同研究时期各流域人均耕地面积减少的幅度却有差异。(4)全省及其4个流域的耕地非农化均以中产田为主,各流域因耕地非农化而造成的粮食损失都较大。

    Abstract:

    Regarding the county territory units situated in 4 hydrologic basins as the research object, the paper explores the effects of arable land scale, the quantity and rate of non-agricultural arable land, and arable land non-agriculture on grain production in different research periods, from the two perspectives of county territory arable land and county territory arable land per capita in Henan Province. The main conclusions are as follows. Firstly, the scale and spatial distribution of arable land in the 4 hydrologic basins were associated with the area and landform of relevant hydrologic basins. Change trend and spatial pattern of county arable land in every basin were different. Secondly, change rates of arable land quantity in most of the counties were negative and concentrated in space in the former research period (1994-1999). However, change rates of arable land quantity in most of the counties were positive and dispersed in the space distraction in the latter research period (1999-2004). Thirdly, the quantity of county territory arable land per capita in four hydrologic basins was reduced, but the reduced amplitudes of arable land quantity per capita were different in the two research periods. Finally, arable land non-agriculture in the province and its four hydrologic basins were given priority to medium yielding field. Grain losses caused by arable land non-agriculture in the 4 hydrologic basins were great.
