通過這些指數的分析表明：甘肅省以草地景觀為主，斑塊數較多，大小斑塊間差異較大，斑塊形狀較復雜，自相似程度較低，
區域總構形較復雜；
區域總構形以大斑塊為主體，呈聚集型分佈，構成景觀主體的是山地丘陵草地景觀和
裸地景觀；隨著人類干擾強度增加，景觀多樣性下降，均勻度降低，景觀破碎化程度加深。

Could there exist another possibility for the south boundary of the system as follow : the rainfall infiltrates in the outcrop carbonate - mountain area of western, and moves towards south and deeper along carbonate rocks, then moves upper through the overlain tertiary system ( n ) with a thickness of 400m ( instead of running off to the springs and yellow river through a long approach of least hydraulic gradient ), and then mainly transforms into the horizontal drainage in the loess layer of quaternary, finally drains in lu - botan depres sion
並且提出，關于對系統南界的認識，是否存在另一可能：即在西部碳酸鹽巖

區大氣降水入滲后，沿碳酸鹽巖向南向深部運動，然後，並非在極小的水力坡度驅動下長距離地向東部黃河、泉群徑流排泄，而是通過上覆厚度約400m的第三系向上運動，繼而主要在第四系黃土層中轉為向南水平排泄到鹵泊灘。
It divides the main vegetation of the headwater region of huangpu river into 4 categories based on field survey and observation and methods of factor analysis and systematic cluster analysis and according to the degree of soil and water conservation function : deciduous trees and shrubs are category 1 which shows very strong soil and water conservation function ; tea plantation, grasslands and pine trees are category 2 which has stronger function ; the category 3 is moso bamboos and broadleaved evergreen trees which have stronger permeability and erodibility, but the permeable performance is not outstanding, the capacity of soil moisture storage common and soil and water conservation function moderate and ; the category 4 is uncovered land where the soil and water conservation function is very weak and its permeability, erodibility, erosive resistance and soil moisture storage capacity are all notably smaller than that of the other lands
摘要在野外調查、實測的基礎上，採用因子分析、系統聚類分析的方法，根據土壤層水土保持功能的強弱，將黃浦江源
區主要植被類型分為4類：落闊林、灌木林為第一類，表現出很強的水土保持功能；茶園、草地、松林為第二類，土壤水土保持功能較強；毛竹林、常綠闊葉林表現出較強的抗蝕性和抗沖性，但滲透性能並不突出，土壤貯水能力也一般，水土保持功能中等，為第三類；
裸露地水土保持性能很差，單獨作為第四類，其滲透性、抗蝕性、抗沖性、土壤水庫容都顯著小於其他各樣地。
The research results mainly show : ( 1 ) the ecological degradation characteristics of wuxi county include : some soil is thin and barren and its water and fertility conservation abilities are poor, gradual degradation of soil results in decrease of vegetation diversity and the vegetation community structure gradually inclines tc simplicity from complexity. the types of soil and water loss in wuxi county mainly involve surface erosion and gully erosion. according to investigation, surface erosion area occupies 80 % or so or erosion area, in which the slope farmlands surface erosion area accounts for about 70 % of farmland erosion area
