【摘要】 研究区属松辽盆地内的断陷平原 ,按区域地质构造、地貌单元及生态类型整体相似 ,可统一将本区划为土壤生态区 ;按区内次级地质构造和地貌单元及生态类型的局部差异 ,将本区划分为剥蚀构造岗丘生态亚区、波状黄土台地 (平原 )生态亚区、河谷漫滩及平坦冲积平原亚区 ;按微地形、成土母质、土壤类型的不同 ,进一步划分土壤生态片。此种划分客观反映了土壤生态条件和生产力的差异 ,有利于土地资源潜力的充分发挥和科学的管理。这是一种新的土地利用规划尝试。更多还原

【Abstract】 This area belongs to sag plain in Songliao basin. The area is defined as soil ecology region according to the whole similarity of the regional geological structure unit, topographical and ecological type. The area is divided as ecological sub regions of erosion structure hill, undulant loessal tableland(plain) and hoya bench and flat alluvial plain according to the sub geological structure unit, sub topographical unit and topic difference in ecological type. Further, each sub region is divided as different soil ecology part accoding to the micro landform, parent material, soil type and society economy condition(geogen). The division reflects differeces of soil ecology condition and produce force objectivily. It contributes to the sufficient exploiration of the latent capacity of land resource and scientific manage. This is a new attempt in land use plan.更多还原
