- 摘要:
- 通过对北部湾经济区5个典型生态系统的枯落物和土壤持水性能进行的研究，结果表明：枯落物累积量为防城港 > 十万山 > 大明山 > 药用植物园 > 金花茶保护区；最大持水率为药用植物园 > 大明山 > 金花茶保护区 > 十万山 > 防城港；最大持水量为大明山 > 十万山 > 金花茶保护区 > 药用植物园 > 防城港；0—20 cm土壤的总孔隙度和毛管孔隙度是大明山 > 十万山 > 药用植物园 > 金花茶保护区 > 防城港，大明山的毛管持水量和最大持水量都最大，分别达到了882.6，954.9 g/kg，防城港最低，只有231.3，269.0 g/kg。
- Abstract:
- Through the study on litter and soil water-holding capacity 5 representative ecosystems in Guangxi North Gulf Economic Zone, the results showed that the accumulation amount of litter was in the order of Fangchenggang > Shiwanshan > Damingshan > Medicinal Herb Garden > Yellow Camellia Natural Reserve; the maximum water-holding rate was in the order of Medicinal Herb Garden > Damingshan > Yellow Camellia Natural Reserve > Shiwanshan > Fangchenggang; the maximum water-holding capacity was in the order of Damingshan > Shiwanshan > Yellow Camellia Natural Reserve > Medicinal Herb Garden > Fangchenggang. The total porosity and capillary porosity in 0—20 cm soil were in the order of Damingshan > Shiwanshan > Medicinal Herb Garden > Yellow Camellia Natural Reserve > Fangchenggang. The capillary and the maximum water-holding capacity were largest in Damingshan, reaching to 882.6 g/kg and 954.9 g/kg, respectively, while the lowest ones were only 231.3 g/kg and 269.0 g/kg in Fangchenggang.
