一般情況下，水資源的變化主要受氣候變化和人類活動的影響，但在位於我國西北內陸乾旱地區的中高山地帶，徑流的形成主要受前者的影響.甘肅省的河西內陸乾旱區是該省重要的工農業生產和經濟開發區，這里各項社會和經濟活動與出山徑流的變化都有著十分密切的關系.因此，筆者根據有關水文氣象臺站的降水、氣溫和徑流觀測資料，分析了以黑河、昌馬河、西營河等主要河流為代表的河西內陸區出山徑流的變化特徵與規律.結果表明，河西內陸區出山口徑流的季節變化主要受地理位置和河流補給來源的影響，而年際變幅則受山區降水量年際變化及變幅的影響十分明顯.目前，梨園河以西河流水量處于上升階段，梨園河以東的河流則處于下降的階段;以黑河幹流鶯落峽水文站年徑流為代表的走廊中部地區的出山口徑流正處於1990年開始的枯水段的上升段.但總體而言，河西內陸乾旱區出山口徑流的變化相對比較穩定.預計今後若干年內，河西內陸乾旱區東段河流出山口徑流的變化以偏枯為主，中段、西段河流出山口徑流的變化以平水或平水偏豐為主The fruit industry starts the structure adjustment in tree species and the varieties. accoring the developmental siuation of fruit industry in shandong, this paper makes a general planning to the location of fruits species, based on the aim to improve competition - ability and estalish a stronger horticultural province, based on some theories and primairy ecological pricilples. in shandong, the apple trees should be 40 %, pear trees 20 %, and neuclear fruit trees 20 %, dried fruit trees 10 %, others about 10 %
針對上述發展形勢，利用農業可持續發展理論、農業區位理論和邊際報酬變動規律與規模報酬等理論，根據「適地適樹」的基本生態原則，按照建設果業強省的整體要求，從全面提高山東省果業競爭力角度出發，我們對山東水果樹種整體布局進行了規劃:蘋果40 % 、梨20 % 、核果類20 % 、乾果類10 % 、漿果類和其它雜果10 %左右。
