Abstract:: To explore the Yulin City green space system of effects of ecological hydrology and characteristics of microbial community, soil physical and chemical properties and nutrient status had been investigated in Dongsha Park, the adjusting function of soil hydrological and richness, diversity and evenness of soil microbial community had been analyzed, water-holding capacity and retention of litter mass had been tested. Results show that:(1) there is a greater difference of nutrition and physical and chemical properties of soils in different areas of Dongsha Park, the bulk densities range from 0.41 g/cm³ to 1.34 g/cm³, the total porosity variation is ranges from 42% to 71%, the contents of organic matter, total nitrogen, total phosphorus, total potassium were 9.93~17.69 g/kg, 0.97~2.37 g/kg, 2.31~6.67 g/kg, 23.6~58.12 g/kg, respectively; (2) characteristics of microbial community was in conformity, tourists area in Dongsha Park significantly impact on the abundance and diversity of soil, the abundance and diversity of Dongsha Park with no disturbance area was higher; (3) soil microbial community structure has nothing to do with sunny or rainy days; (4) reserves of litter mass of different areas have significant differences in the green space of Dongsha Park, the thickness of litter mass was the largest in the green space surface of parking area and disturbance area, the thickness of litter mass was the minimum in pavement, reserves also had similar discipline. To sum up, it is important for favorable city ecology to maintain soil and litter mass, it needs to strengthen the protection of environment, and reduce human interference and damage of green space.
