红松洼自然保护区草地群落物种多样性和土壤肥力与地上生物量的相关性研究
The grass species diversity and soil fertility research of biomass on the ground of Hongsongwa Nature Reserve
摘要
Abstract
The relationship between biodiversity and biomass has become an important problem in modern ecology research.Plant growth and development are related with soil factors.We took Hongsongwa Nature Reserve as an example, to investigate the relationship by analyzing the plant species, quantity, height, and coverage, as well as the parameters including soil water content, organic matter content, total nitrogen, and total phosphorus content.The results showed that species diversity and above biomass of grassland were significantly and positively correlated (P<0.05) ;the grass species diversity index and evenness index and above biomass of grassland also were significantly and positively correlated (P<0.05).Soil moisture and soil total nitrogen content were not related with the above biomass of grassland (P>0.05), positively related with the soil organic matter content (P<0.05), but negatively related with soil total phosphorus (r<0).The biomass of grassland can be increased by increasing species diversity and soil organic matter content.关键词
