为研究巴图湾水库库区实施防沙措施后土壤与植被的特征,选取了库区的尼龙网沙障、草方格沙障和草绳沙障,采用野外调查和室内分析的方法,对不同程度沙障内的植被及土壤指标进行了测定,初步得出:不同保存程度的尼龙网沙障植被长势存在差异。尼龙网沙障内粒度组成以中沙、细沙为主,细沙含量高于中沙。草方格内沙土0-30cm的中沙和细沙含量最高,30-50cm细沙含量最高,中沙次之,上层较深层沙粒粗。草绳沙障内沙土的粒度组成与尼龙网沙障结果相似,细沙含量最高,中沙次之。三种沙障的土壤全N、全P、全K的含量均较低,无明显差别。沙蒿地上生物量与有机质的变化趋势变化基本一致。
In order to study the characteristics of soil and vegetation after the sand control measures were implemented in the Batuvan reservoir area, nylon sand barrier, grass grid barrier and sand barrier of the reservoir area were selected. Field investigation and indoor analysis were used to determine Vegetation and soil indexes in different degrees of sand barrier were measured. The results showed that there were differences in the growth of nylon sand barrier with different storage levels. Nylon net sand barrier particle size to sand, fine sand-based, fine sand content is higher than in sand. Grass squares within the soil 0-30cm in the highest content of sand and fine sand, sand content of 30-50cm highest, followed by sand, sand deeper coarse upper. Grass rope sand barrier sand particle size composition and Nylon net sand barrier results similar to the highest content of fine sand, followed by sand. Three types of sand barrier soil N, P, K content were low, no significant difference. The aboveground biomass of Artemisia sphaerocephala was almost the same with that of organic matter.
