- Abstract:
-
The effect of wind power site construction on vegetation and soil nutrients of the surrounding disturbed region were examined. The results showed that the wind power site construction increased soil bulk density, pH and total porosity, reduced the soil electrical conductivity, moisture content and total salt in the surrounding disturbed region, at the same time, it reduced the growth of the vegetation index and soil nutrients (in addition to the soil total phosphorus) and so on. In disturbed region (0~3 km), the index of plant growth and soil nutrients increased with the increase of the distance from the wind power site, When distance is 4 km away from the wind power site, the index of plant growth and soil nutrient in disturbed region were consistent with non-disturbed region, which turned out that the effect of wind power site on vegetation and soil nutrient was within the scope of 3 km, in addition, the range ability and coefficient of variation of soil microbial biomass were the largest which meant the influence on the spatial variation of soil microbial biomass was more significant than other soil nutrients. In disturbed and non-disturbed region, the soil nutrients decreased progressively with soil depth and showed the enrichment in surface soil layer which meant that surface accumulation was obvious, while at the layer of 40—60 cm, the soil nutrients in disturbed and non-disturbed region had no significant differences, which indicated that wind power site construction had no influence on the vertical distribution characteristics of soil nutrients and the soil nutrient content of deeper layers. Pearson correlation analysis showed that wind power site construction had the same effect on vegetation and soil nutrient of the surrounding disturbed region, which meant that wind power site influenced the plant and soil nutrient at the same degree and reflected the complex interaction effect of vegetation and soil nutrients.
