| 摘 要： | 运用景观生态学的基本原理,分析黄河滩区1975—2000年景观格局演变特征.结果表明,旱地、滩涂、建设用地和河流景观类型为占优势的景观类型.1975—2000年,景观格局动态变化显著:旱地景观类型面积增大,滩涂和河流景观类型面积缩减,建设用地景观类型面积持续增加,草地和沙地景观类型的面积随着河流景观类型的变化和人类活动的影响而变化,景观空间特征表现为景观多样性在前两个阶段减小,而最后一阶段略有增大.景观空间构型明显,基本上是以大斑块为主,呈聚集型分布.人类活动对黄河滩区景观的变化有重要的影响.

| Abstract: | By using GIS and a series of preliminary group interviews,the paper discussed how nature and human activities have influenced the beach areas landscape pattern change from 1975 to 2000.The results showed that: within the study area,the dry land,beach,built areas,and rivers were the dominant landscape types.From 1975 to 2000,there were increases in the area of the dry land and built areas classes,while the area of landscape types classified as beach and rivers decreased.At the same time,the area of grass and... |
