Parallel Climate Model Effort (Version 1) This is a joint effort to develop a DOE-sponsored parallel climate model between Los Alamos National aboratory (LANL), the Naval Postgraduate School (NPG), the US Army Corps of Engineers' Cold

CCCma has develped a number of climate simulation models for climate prediction, study of climate change and variability, and to better understand the various processes which govern our climate system. A brief description of these models and their corresponding references can be found in this section

HadCM3--Coupled atmosphere-Ocean general circulation model HadCM3 is a coupled atmosphere-ocean general circulation model(AOGCM)developed at the Hadley Centre and described by gordon et al (2000)and Pope et al (2000). Unlike earlier AOGCMs at the Hadley

一、盐碱化的概念及产生原因 (一)盐碱化的概念 土壤盐渍化(土壤盐碱化)是指盐分不断向土壤表层聚积形成盐渍土的自然地质过 程。盐渍土是在一定的气候、地形、土地、水文地质等自然条件下形成的。人类活动、历 史上的洪、涝、旱灾害,河道变迁,以及土地利用、农业、水利技术措施等,又对土壤盐 渍化的发生、发展产生重大影响。 一般将土壤层0.2m厚度内可溶盐含量大于.1%的土壤称为盐渍土。土壤盐渍化分 化与碱化两种类型,故又称为土壤盐碱化。当土壤表层中的中性盐含量超过0.2%时,称为 盐化土(盐土);以碳酸盐为主的盐渍土,土中代换性钠含量大,通常称为碱化土(碱 土)。土壤盐渍化主要发生在干旱与半干旱地区
