摘要
本文以北京天坛公园为试点,通过对土壤的堆垫情况、容重、坚实度、孔隙状况、水分状况及土壤动物活动形成的孔洞分布等项的测定和分析,初步探讨了园林土壤物理性状的变化规律,并提出了有参考价值的数据和改土建议。
We investigated the soils of Beijing TianTan Park, by means of analy-
sing and testing the Pile-up case, volume weight, degree of Campaction,
porosity, soil water vegime and the distribution of holes formed by soil
animals. The variation regularities of soil physical regime of this garden
soil were reseached initially. Some referential data and suggestions for
soil amelioration were put forward.
