科尔沁沙地植被恢复系列上群落演替与物种多样性的恢复动态 - The structures and dynamic changes of the artifical sand - fixing vegetation were studied based on the follow views : components of vegetation community , plant diversity , life - forms of vegetation , trends of plant growth , characteristics of the vertical and horizontal structure of vegetation , relationship between the vegetation community and environment ( including soil moisture temperature etc . ) , relationship between the vegetation community and characteristics of plant physiological activities . some results were showed as follow : 1 . components , diversity and life style of artificial vegetation in shapotou region the marked changes of artificial vegetation have taken place during more than 40 years , since the establishment of sand - fixing vegetation
本文以腾格里沙漠东南缘宁夏中卫县沙坡头地区人工固沙植被作为研究对象，采用传统生态学的野外调查方法，从植被群落的组成、多样性、生活型、群落生长动态、垂直结构特征、水平结构特征、群落结构与周围环境(土壤含水量、温度)相互关系及其与植物自身生理生态适应特征关系等多个角度研究了人工植被群落的结构及其动态变化，取得了如下研究结果： 1 、植被群落组成、多样性及生活型：沙坡头地区人工植被经过近50年的演变，从流动沙丘到固定沙地，沙地植被的动态变化经历了从人工植被到人工?自然植被的转变，从人工植被建立初期的少数几种引种植物到现有30多种植物，随着固定沙地时间的延长，植物种类日趋丰富，并且人工植被在15 25年、 40 50年两个阶段，物种的周转速率最大，即群落结构变化最大。
