摘要
双鸭山市是以生产煤炭为主的新兴工业城市,生态景观特色明显,矿产、植被、耕地资源丰富,该区域生态环境复合多样,因此研究生态功能分区可以将双鸭山市划分成多个生态功能区,针对各个区域进行生态保护,对双鸭山市生态环境建设有着重要的意义。生态分区的主要方法是指标的选取和界限划定的方法,本文运用Erdas、ARCGIS软件对双鸭山市遥感影像、土地利用数据库进行叠合分析,运用定性和数量分区将双鸭山市划分成三大生态功能区,分别是:森林涵养水源生态功能区、生物多样性保护与农田生态功能区、丘陵漫岗水土保持生态功能区。揭示了不同区域土地生态环境状况、土地利用方式,以便于确定不同区域土地的主导用途,调整土地利用方式和土地利用结构。为合理利用土地资源、改善生态环境服务,也为各个级别规划进行地域分区提供科学依据。
Shuangyashan is an emerging industrial city which is popular with coal.The ecological landscape feature is clear,and it is rich in the minerals,vegetation,and land resources.The region environment is complex diversity,so it can be divided into several ecological functional zones for researching.It has a great significance for the ecological environment constructing of Shuangyashan to protect the environment according to different conditions of different zones.The main method of dividing ecological zones is target selection and delimitation,and this thesis applied ERDAS,ARCGIS software to analyze Shuangyashan remote sensing image and land-use database.Shuangyashan could be divided into three ecological functional zones by qualitative and quantitative methods：water conservation of forest ecological functional zone;biodiversity conservation and agro-ecological functional zone;hilly Mangang soil and water conservation ecological functional zone.It showed the different environment conditions and land use pattern of different regions,and was easier to determine the dominant use of land in different regions and to adjust the land use pattern and land use structure.It served for the reasonable use of land resources and improving ecological environment,but also provided a scientific basis for territorial partition of all the levels.
