渭北台塬区不同景观林对土地整治新增土地土壤团聚体特征的影响研究——以石川河综合整治项目为例

Effects of Different Landscape Forest on Characteristics of Land Soil Aggregates Under Weibei Plateau After the Implementation of the Land Consolidation Project: The Ishikawa River Comprehensive Renovation Project as an Example

以探明不同景观林对土壤团聚体的影响为目的,为"生态型土地整治"的快速发展提供科学依据。在富平石川河综合整治项目区,本研究测定分析了干筛法和湿筛法下0—40 cm土层土壤团聚体分布、平均质量直径(MWD)、几何平均直径(GMD)、团聚体破坏率(PAD)、不稳定团粒数(ELT)和分形维数(D),选取4种不同的土地利用方式开展相关研究试验。

To reveal the influence of the different landscape forest on soil aggregate, provide a scientific basis for the rapid development of ecological land consolidation. In Fuping Ishikawa River comprehensive renovation project area, we analysis of wet sieve method and dry sieve of 0--40 cm soil layer soil aggregate distribution, average quality diameter （WMD） and geometric mean diameter （GMD）, aggregate damage rate （PAD）, the number of unstable crumb （ELT） and fractal dimension （D）. and set up four different ways of land use to research of test.
