坡地是三峡库区主要的地貌类型,库区坡地资源的地表层质地、植被、气候、水文等环境特征决定了其生态环境的脆弱性,容易产生水土流失。坡地的开发利用关系到三峡库区是否可持续发展。由于人们需求的不断扩大,使坡地资源开发日益增加,文章从坡地系统的物质能量出发,针对稳定坡面、较稳定坡面、较不稳定坡面与强烈不稳定坡面提出四种开发模式。
坡地是三峽庫區主要的地貌類型,庫區坡地資源的地錶層質地、植被、氣候、水文等環境特徵決定瞭其生態環境的脆弱性,容易產生水土流失。坡地的開髮利用關繫到三峽庫區是否可持續髮展。由于人們需求的不斷擴大,使坡地資源開髮日益增加,文章從坡地繫統的物質能量齣髮,針對穩定坡麵、較穩定坡麵、較不穩定坡麵與彊烈不穩定坡麵提齣四種開髮模式。

Slope land is primary physiognomy types in Three Gorges Reservoir Area.Its environmental characteristic of surface texture,vegetation,climate and hydrologic character determine frangibility of its eco-environment and easily cause water and soil loss.Developing and using slope land relate to whether Three Gorges Reservoir Area can sustain development.With people＇s demand increasing,development of slope land resources increasingly strengthens.From view of matter and energy,the paper brings forward four development modes aimed at stable slope,rather steady slope,rather unstable slope and unstable slope.
