中文摘要就四川盆地西部白垩系灌口组(K2g)母岩发育紫色雏形土的特征及其基层分类进行了研究。发现盆西K2g紫色雏形土在理化性,肥力和生产性上都有一些特点。采用专家系统建立了紫色雏形土基层分类指标体系,提出以三维指标进行土壤基层分类的新方法,以此对该土壤土系划分进行尝试。
英文摘要About 100,O0 ha of purple Cambisol derired from K2g purple parent rock is distributed
in the west of Sicbuan basin.which accounts for 4.3% of soil area in SichUall basin and is the ODe Of main agriculture soil in west Sichuan.The characteristics of this kind of s。il are :reddish soil color,mostly red—brown oolor(2 5 YR or 10 R);higher aJ330u~t 0{soil clay particle (<0.002 n】丌1),sortie20-32% ;normally highermnount 0ftime,CaCO3 content being16.4~ 61 6g/kg,PH of m il reaction 7.6~ 8.7;reasonable soil fertility in texture,structure,.soillxxty type and productivity.
The distinction of soil species for basic K2g pu叫e Cambiso]classification was in the
light of texture,thickne~ of soil horizon and soil fertility According tO above three criteria
the basic soil species were determined by establishing soil dassifying principles and three dimension methods for species classification.Then the local name in that this soi1 species WaS diseoveved Was put in front of the term for this basie soi1 species .Dividing for several so ll spedes,K2g purple Cambisol could indicate the actual soil situation with the advan tages of quantitative criterion,science in indexing and applica tion in agriculture.So this classification method should he researched further and spreaded for application.
