Based on the detailed research on the sedimentary rocks of northwest ordos basin in their textures, structures, vertical sequences and logging response, six kinds of sedimentary facies can be recognized in this work, i. e., alluvial fan, stream, fan delta, braided delta, delta, lake, barrier beach and carbonate platform, respectively, and more detailed classification of sedimentary subfacies and microfacies for each sedimentary facies are also made in the work
本文通過對鄂爾多斯盆地西北部沉積巖沉積結構、沉積構造、垂向序列及測井響應的深入研究，識別出沖積扇、河流、扇三角洲、辮狀河三角洲、曲流河三角洲、湖泊、障壁海岸及碳酸鹽臺地等8種沉積相類型。在此基礎上，對每一種沉積相又進行了詳細的沉積亞相和微相的劃分。 -
It decides the protective objectives for different ecological reserve area based on the study of channel wetlands and survey and analysis of top - grade species ( fishes ) of the yellow river : from the point of the basin, the main ecological protective objectives of the tipper stream are vegetation and forest for conservation of water supply ; soil and water conservation is the main in the middle reaches for vegetation protection and rehabilitation and ; the lower reaches takes types of wetlands protection and wetlands area maintenance as the main, protecting biodiversity and important birds resources
在黃河河道濕地研究和黃河水體內頂級物種（魚類）的調查分析基礎上，確定了黃河不同類型生態保護區的生態保護目標：從流域角度而言，黃河上游的主要生態保護目標是植被和水源涵養林；中游應以水土保持為主，主要是恢復和保護植被；下游以保護濕地類型和維持濕地面積為重點，保護生物多樣性和重要鳥類資源。 -

In view of the existing problem in the traditional method of the compartmentalization of urban rainwater catchments basin, by the technology of partition of drainage basin and professional gis terrain disposal software, the paper proposes a method of automatically compartmentalizing the urban rainwater catchments basin by six steps : construct the grid dem, define the stream direction of grid nod, extract the catchments network, compartmentalize the sub - catchments, build urban rainwater catchments basin with sub - catchments, encode the rainwater catchments basin
摘要針對傳統匯水區劃分方法中存在的問題，利用流域地形分割技術，通過專業的gis地形處理軟體，建立了城市雨水流域匯水區的自動劃分方法，其劃分過程主要由構建格網dem 、格網點流向定義、匯流網路提取、子匯流區域劃分、子匯流區域生成城市流域匯水區和流域匯水區編碼6步組成。 -
On the basis of raster digital elevation model ( dem ) data over the laohahe river catchment in the upper and west area of the liaohe basin within inner mongolia autonomous region, the digital elevation drainage network model ( dednm ) is applied for assigning flow - vector directions over flat and depressional areas of the dem, for identifying stream network and watershed divides, and for establishing spatial topological structure of subcatchments and stream network
基於遼河水系老哈河流域柵格數字高程模型（ dem ）數據，採用數字流域水系模型（ dednm ） 、河流工具rivertools 、地理信息系統arcview軟體，根據地形提取水系信息，構建數字流域水系、子流域與河網的空間拓撲關系。
