摘要

本研究的目的是计算与土壤质地相关的SPI(水流功率指数),并将所得值与土壤渗透性等级联系起来,从而确定排水过程作用下的脆弱区域,从与细沟侵蚀和沟壑相关的基本过程开始,到那些沟壑和暴雨生物。SPI是坡度与水流累积的乘积。SPI值受斜率的影响。因此,在坡度高的地区,SPI值高,在坡度低的地区,SPI值低。在坡度高的地区,流量积累较少,而在坡度低的地区,流量积累较多。SPI值在+1.94 ~ +3.49之间的高值区位于Lipovei Hills南坡,占分析区面积的41.05%。将土壤质地纳入SPI计算公式表明,在Lipovei Hills南坡,SPI也处于中等水平,占研究区域的42.71%,与壤土质地相对应。泥质结构具有中等渗透性,在利泊韦丘陵南坡占22.81%。因此,利波维依山南坡受中度沟壑现象影响,与Timiș-Bega平原接触处发育洪水和水坑现象。

VULNERABLE AREAS, THE STREAM POWER INDEX AND THE SOIL CHARACTERISTICS ON THE SOUTHERN SLOPE OF THE LIPOVEI HILLS
The purpose of this study is to calculate SPI (Stream Power Index) in relation with the soil texture and to associate the obtained values with the soil permeability classes and, therefore, to identify the vulnerable areas at the action of the drainage processes, starting by the elementary processes associated with rills erosion and gullys to those ravines and torrential organisms. SPI is the product between the slope and the flow accumulation. SPI values are influenced by the slope. Thus, SPI has high values in areas with high slope and SPI has low values in areas with low slope. In the areas with the high slope, the flow accumulation is low and in the areas with the low slope, the flow accumulation is high. The high values of SPI between +1.94 and +3.49 are on the southern slope of the Lipovei Hills and represent 41.05% of the analyzed area. The inclusion of the soil texture in the SPI calculation formula indicates a medium value of SPI also on the southern slope of the Lipovei Hills and represent 42.71% from the studied territory, which corresponds, in particular, to the loamy texture. The loamy texture has moderate permeability and it is characteristic on 22.81% from the southern slope of the Lipovei Hills. Therefore, the southern slope of the Lipovei Hills is affected by the moderate ravine phenomenon and at the contact with the Timiș-Bega Plain the floods and the puddles phenomenon develops.
