Influence of different sampling strategies on the relationship of biodiversity and grassland primary production

摘要：

The relationship between biodiversity and ecosystems function (primary production shown in most studies) is a key issue for ecologists.The maximum community biomass in August was used as production in almost all studies.Some researchers suggested that a multi‐harvest sampling strategy may be better in grassland communities ( Hooper and Dukes, 2004 ).A three‐year study was conducted in a natural grassland community to test the influence of the sampling strategy on the relationship between biodiversity and grassland primary production.
