摘要

以吉林省西部土壤退化典型地区大安市和长岭县为例

研究、分析了该地区土壤退化特征及机理。该地区的土壤退化主要表现为营养成分的减少

有害的盐碱成份的增加。造成土壤退化的原因既有自然因素也有人为因素

自然因素是土壤退化的基础和潜在因素

人类不合理活动是土壤退化的诱发因素和主要因素。借助于GIS

SPSS技术

揭示了土壤化学成分在水平、垂直方向的动态变化和分布规律。该区的土层结构复杂

土壤剖面含盐量的分布呈“T”形、正“梯”形、负“梯形”和“柱”形等形态。

Abstract

The characteristics and mechanism of soil degradation were analyzed

as the case study of Da'an city and Changling county in the west part of Jilin province. Soil degradation in this region mainly expressed decrease of nutrition element and increase of salt and alkali. Soil degradation had been caused by natural factors and human impacts. Natural factors were potential and human activity was to enhance potential soil degradation. With application of GIS and SPSS

it was analyzed that dynamical change and horizontal and vertical distribution of chemical elements. Soil horizon structure was complex. Soil salt content in soil profile expressed T shape

straight trape-zoid

reverse trapezoid

and column shape.
