摘    要:在GIS支持下,利用TM卫星遥感影像提供的信息以及非遥感信息相结合的方法,获得研究区景观生态类型和生态环境现状数据资料,利用景观生态学模型获得研究区景观格局特征指数,对比分析了呼和浩特市域两个典型的风蚀沙化和风水两相侵蚀沙化地区一一石质低山丘陵区和黄土丘陵区的景观格局特征.结果表明,呼和浩特市典型地段土地沙化和景观格局特征(特别是农田景观)与人类活动强度密切相关;生态建设是目前以及将来防止土地进一步沙化,促进地区社会经济发展,保证呼和浩特市生态安全的重要手段;宏观控制区域景观格局变化和微观实施生态工程建设同步进行是遏止土地沙化的根本出路。

关 键 词:景观格局  土地沙化  丘陵区  生态建设

Abstract:On support of GIS,with RS and other information,data of present situation of landscape ecological type and ecological environment was obtained. With landscape ecology models, characteristic value of landscape space pattern in research area was gained, characteristic of landscape space pattern in the northern low mountain stony knoll and hill area with the southern loess hill area in Huhhot city district which are typical desertification of wind and water erosion was contrasted. The results showed that human activities have important impact on change of ecological environment at resent, especially on change of farmland landscape pattern. Ecological constructions are important ways of preventing desertification,improving ecological environment ,promoting social and ecological security. It is fundamental method to control the change of landscape pattern of region and to enforce ecological engineering construction macroscopically.
Keywords:landscape pattern  land desertification  hill area  ecological construction
