摘要: 本文在对无定河中游左岸监测区流域内农林业生产基地及主要农业作物进行详细调研后,选取不同地形结构(坡地、梯田和坝地)、不同措施配置(乔木林、灌木林)等10种农业用地的地类,进行土壤理化指标监测,并对监测结果进行横向和纵向两个层面分析,发现各种地类的各类指标均存在着不同水平的退化趋势,并针对问题提出了3项治理措施。

Abstract: In this paper, a detailed investigation of the Wuding River Basin in the middle reaches of the river left bank monitoring area of agricultural production base of forestry and the main agricultural crops in, choose different topographic structure (slope, terrace and dam), different measures configuration (arbor, shrub) and other 10 kinds of agricultural land into land type, soil physicochemical index monitoring, and the monitoring results are analyzed with two horizontal and vertical level, find all kinds of index of each class there are the trend of degradation of different level, and proposes 3 measures to solve the problem.
