  3. The research result is following : the annual species richness index of studied forest plant community averaged 64. 688, the species diversity index was 2. 982. the proportion of every functional group of forest plant community is : herbaceous layer ( average is 68. 89 % ) > tall tree layer ( average is 15. 266 % ) > shrub layer. ( average is 15. 845 % ) the proportion of every functional group in forest insect communities is remarkably different, and the order of the proportion is herbivorous insect group ( average 0. 729 ) > predatory natural enemy insect group ( average 0. 136 ) > parasitical insect group ( average 0. 135 ). with seasonal change, the proportion of herbivorous and predatory insect group decreased obviously, while that of parasitical insect group increased on average by 147 %

    研究結果如下：森林植物群落種的全年物種豐富度指數平均為64 . 688種，多樣性指數為2 . 982森林植物群落內各功能類群物種所佔比重依次為：草本層（平均為68 . 89 ） >喬木層（平均為15 . 266 ）灌木層（平均為15 . 845 ） 。森林昆蟲群落中，全年各功能類群所佔比重以植食性昆蟲類群為最大，平均佔0 . 729 ；捕食性昆蟲類群次之，平均佔0 . 136 ；寄生性天敵類群為最小，平均為0 . 135 。

  5. Meanwhile, most aspects about this perspective are concerned, which include quantification of the soil water background of the plateau area, the regional spatial variation of soil water background and variation along the slope, mosaic structure and seasonal changes etc. the results show that : ( 1 ) for the fundamental circumstance for vegetation development is the original debilitated slope, so the perspective of soil water background specially for the loess plateau refers to the soil water conditions on the original slope. ( 2 ) the value of soil water background appears to be a descending trend from south to north based on the difference of vegetation zones. in the forest zone, soil moisture contents beneath 3m depth from the soil surface are more than 12 % usually ; in the forest - pasture zone, the values of soil moisture content beneath 4m depth underground are more than 6 % and stable, and tend to be ascending while the depth increases ; but the values in the dry pasture zone is lingering between 4 % to 6 % from the surface layer to sub - layers

    發展了「土壤水分背景」的概念，並以之為基礎對其各個方面進行了研究，使之形成一個相對獨立和完整的體系，主要包括黃土高原土壤水分的背景值、土壤水分背景的區域分異、坡面分異、鑲嵌結構及其季節分異等： （ 1 ）由於植被生長發展、演替的基礎階段是天然草被群落，故認為黃土高原的土壤水分背景在概念上是特指該區天然草被群落下的土壤水分狀況； （ 2 ）黃土高原的土壤水分背景值，根據植被地帶的不同表現出自南向北逐漸降低的規律：森林地帶3米以下土層水分背景值普遍穩定地高於12 ，森林草原地帶4米以下土層水分背景值穩定大於6 ，且均隨土層的加深水分含量逐漸增加，而草原帶的土壤水分背景值自土表至底土層一直在4 6之間徘徊。
  6.

    採用層次分析法對酒泉綠洲畜牧業發展的重要影響因素做了判斷。最後從確定合理的載畜量，大力保護草地資源和發展優質人工草地，實施虛擬水戰略以緩解酒泉綠洲的生態環境壓力，大力推進畜牧業產業化進程，對農區農作物副產品的加工利用、加強祁連山防護林建設、組織畜牧業季節性生產，推廣推廣肉禽異地育肥技術、加強畜牧業生產的合理規劃、增加資金投入，加快畜牧業基礎設施的建設以及草原鼠害的防治等十個方面提出了酒泉綠洲畜牧業發展的具體對策建議，以期望能對酒泉市的社會經濟發展提供科學的決策依據。
  7. The east transect was classified thirty five vegetation types using ndvi data from 1995 - 1996 by gis technique. the paper concludes that the ndvi from meteorological satellite is sensitive indicator of vegetation growing condition, times series curves of ndvi can truly curve vegetation growing principle by drawing the seasonal change curve of ndvi data by three groups. the paper also concludes that the forest ' s ndvi curve is commonly single apex, while farmland ' s or shrub ' s curve is mostly double apex, the peak value of forest ' s ndvi is commonly higher than grassland, farmland and some other vegetation types

    應用地理信息系統技術處理1995 - 1996年1kmndvi數據，將南方樣帶劃分為35類，分三組繪制35類植被的ndvi季節變化曲線，得出氣象衛星ndvi是反映植被生長狀況的敏感指示器， ndvi時間序列曲線真實地刻畫出植被的生長規律；經分析得知森林ndvi曲線一般為單峰曲線，而農田灌叢多為雙峰曲線；森林ndvi峰值一般高於草原、農田等其它類型。
