| 摘 要： | 本文对广西英罗港自然保护区不同红树植物群落土壤主要性质进行了较系统的研究。结果表明 ,英罗港不同红树植物群落土壤理化性质和酶活性均存在明显差异 ,土壤粘粒粉粒含量和有机质、全氮、水解氮、全磷、速效磷及盐分含量为 :木榄群落 >红海榄群落 >秋茄群落 >桐花树群落 >白骨群落 ;土壤蔗糖酶、蛋白酶、脲酶、酸性磷酸酶 4种水解酶和过氧化氢酶的活性大小顺序为红海榄群落 >木榄群落 >秋茄群落 >桐花树群落 >白骨壤群落 ,多酚氧化酶则与此相反 ;土壤养分含量和土壤水解酶以及多酚氧化酶活性均随剖面深度而降低 ,过氧化氢酶则呈相反趋势。英罗港红树植物群落土壤酶活性与土壤肥力因素密切相关 ,各土壤酶活性之间也存在不同程度的相关性。因此 ,土壤酶活性可以作为该土壤肥力的指标之一。

| Abstract: | This paper deals mainly with the properties of the soil of the mangrove in Yingluo Bay Natural Reserve of Guangxi. The results showed that the soil physical and chemical properties and enzyme activities differed obviously between five mangrove communities in Yingluo Bay. The contents of soil silt, clay, organic matter, total N, total P, hydrolyzable N, available P and total salt were in the order of Bruguiera gymnorrhiza community > Rhizophora stylosa community > Kandelia candel community > Aegiceras corniculaturn community > Avicennia marina community. The hydrodase activities of invertase, protease,urease and acid phosphatase and oxido xeductase activity of catalese in soils were in the order of R.stylosa community> B.gymnorrhiza community> K.candel community> A.corniculaturn community> A.marina community, but polyphondel oxidase in soil was at the contrary. The contents of nutrient factor and enzyme activities (except catalase) in soils were decreased with increasing soil depth. Enzyme activities in soil were closed related to soil fertilities. There are also correlation among different enzyme activities. So enzyme activity could be used as an index for evaluation of tidal flat soil fertility. |
