中国东北样带生态环境区划研究

Study on Eco-environment Regionalization in the Northeast China Transect (NECT) Based on RS and GIS

从国内外生态区划、生态土地分类和生态-生产范式的研究和发展入手,从生态利用的角度出发,以生态要素区划为基础,依据自然生态因子(如:气候、地形地貌、植被、土壤)和人类活动(如:土地利用)的特点,运用经验判别法和RS与GIS技术进行生态环境综合区划,将中国东北样带分为5个生态环境区,命名方式采用地理位置+地貌类型+干湿状况+土地利用组合状况。即:长白山中低山湿润针阔混交林生态环境区、牡丹江-辽源低山丘陵湿润农林交错生态环境区、大青山-大黑山山前台地湿润半湿润农业生态环境区、松嫩平原半湿润半干旱农牧交错生态环境区、内蒙古高原东部草原干旱半干旱牧业生态环境区。

According to the study on eco-environment regionalization, the ecological land classification and eco-productive paradigm home and abroad, this paper develops an eco-environment regionalization system for the Northeast China Transect （NECT） based on ecological and environmental factors, including climate, terrain features, physiognomy, vegetation, and soils, in combination with characteristics of human activities （ such as land use）. The region is stratified into five discrete geographical units. Each unit is named as the location ＋ physiognomy type ＋ the dryness and humidity state ＋ land use pattern. They are the humid theropencedrymion ecotope in the medium and low mountain of Changbai Mountain, the humid farm-forest ecotope in the low mountain of Mu Danjiang and Liao Yuan, the humid and semi-humid agricultural ecotope in pediment tableland region of Daqing Mountain and Dahei Mountain, the semi-humid and semiarid ago-pastoral ecotope in Songnei Plain, the arid and semiarid pasto- ral ecotope in the eastern Inner Mongolia Plateau.
