河北坝上沙漠化地区土壤特性研究——以丰宁试验区为例

摘要/Abstract

摘要： 本文分析了丰宁试验区土壤类型、分布特点、成土条件、土壤养分、可溶性盐分、机械组成、矿物元素含量、微量元素、水分状况,并对各类土壤的生产力进行了评价。结果表明:栗钙土是本区生产力最高的土类,风砂土是栗钙土退化的产物,也是栗钙土重新发育的不同阶段,这种退化主要是土壤中细颗粒物质及养分的损失,而土壤矿物元素、微量元素并无明显变化。本区风砂土相对其它典型沙地生产力较高,与地带性土壤栗钙土相比无钙积层,适宜多种深根性植物特别是乔灌木的生长,所以本区目前沙漠化土地治理相对容易。

Abstract: This paper analysed the soil types,distribution features,soil-forming conditions,soil nutrient,mechanical composition,mineral element contents,soluble salts and moisture condition and evaluated the productivities of different soil types.The results showed that the chestnut soil is the local soil group with highest productivity,while the aeolian sand soil is the degraded product of chestnut soil or the different development stage of re-developed chestnut soil.Soil degradation in the region is manily manifested in the losses of fine particles and nutrient elements.Aeolian sand soils in the region have a relatively higher productivity than typically zonal sandy soils but they have no caliche as compared with zonal chestnut soil.They are suitable for cultivation of deep-rooted plants,such as trees and shrubs etc.
