  4. 3 the author analyzes the productive and opening potential and forecasts the demands of some kinds landuse and draws some conclusions : ( l ) the main cause for low production and income is the shortness of water and the poor fertility of land ; ( 2 ) constructive land is not suitable for farming and should be used for economy construction, and this is the main path to keep the total number of plantation in balance. 4. according to the land use, the author discover the unsustainable factors and use synthetical index method to evaluate the sustainability of landuse and the results are these : ( l ) synthetical and monomial value increase gradually with the change of time and sustainable degree of landuse rises year by year ; ( 2 ) the artical compartmentalizes the sustainable landuse into four grades : prophase, primary period, basic period and sustainable period according to the synthesical value with 30 %, 60 % and 85 %

    4根據酉陽縣土地資源利用現狀，在評價模型採用綜合指數法進行評價的基礎上，結合單指標多角度評價法，找出土地利用過程中存在的不可持續性因素，採用綜合指數法對酉陽縣土地資源進行可持續利用評價，結果顯示: （ l ）綜合評估值隨時間變化呈增加的趨勢，而且單項指標的評估值也逐漸提高，可持續利用度在逐年上升; （ 2 ）根據事物發展階段論，按綜合評估值為30 % 、 60 %及85 %將酉陽縣土地可持續利用劃分為可持續利用的前期階段、初期階段、基礎階段和持續階段等四個等級，從酉陽縣1980年、 1990年以及2000年總的土地可持續利用綜合評估值來看，酉陽縣到2000年土地利用管理仍處在可持續利用管理的初期階段，離土地可持續利用的目標還相差較遠。
