Study of the Exploitation and Utilization of Land Resources of Jiazihe Small Watershed in the hilly region of West Henan

通过对土地构成要素的分析，根据土地质量的特点和差异性，对豫西黄土丘陵区架子河小流域的土地资源进行了系统分析评价。根据该区特点，主要选择了坡度、土层厚度、砾石或砂姜含量和灌溉条件４项指标，进行了土地分级，根据土地利用现状和生产实际中存在的问题，提出了各级地的合理开发利用方向和途径。

According to the analysis of the essential constructured elements of land,considering the characteristics and differences of land qualities,we have systematically analysed and assessed the land resources of Jiazihe small watershed in the hilly region of West Henan.According to the regional peculiarities,the land is graded in terms of four index,including the degree of slope,the thickness of soil layer,the content of grit and the condition of irrigation.Considering the present situation of land utilization and problems existing in agricultural production in all types of land,certain reasonable exact ways and tendency of exploitation and utilization are suggested.
