摘要 Local plants were important for ecosystem diversity,of which herbaceous plants took a great account. In the article Fushi Village and Saoshe Village in Zhejiang Province were taken as test plots,where land use systems were divided into four artificial habits such as artificial forest,gardens,rivers,farming area for comparing plant diversity under different artificial habits,and three parameters such as Shannon-Wiener index,Simpson index,Sorensen index were employed. The results showed that based on the investigation,there were 162 species including 47 families,123 genera,were found in all the habits. The principal species was from Compositae and Gramineae,accounted for 31.48% of the total. The highest plant diversity was in farming area,Shannon-wiener index value reaching 2.76 and Simpson index value being 0.91,Sorensen index value of 0.57,the same with rivers. From the farming area,rivers,gardens to artificial forest habitat,the value of herbaceous species diversity overall decreased. Moreover,taking greening measures would lead to herbaceous species reduction. For example,from the paddy field to farming area habitat,the main herb family and genus composition did not change significantly,plants of Cyperaceae,Compositae and Gramineae still occupied the main body. The composition of the main species of herbaceous plant community had changed,the herb species of Cyperaceae,Compositae and Gramineae were 11,8 and 15 in the paddy field habitat,Cyperaceae,Compositae and Gramineae species were 4,19 and 17 in the farming area habitat. Comparison of two kinds of habitats in herbaceous species composition,species number of cyperaceae reduced,compositae species number increased. Additionally,Alternanthera philoxeroides,Solidago canadensis and Dysphania ambrosioides,total three invasive species were found in four habitats,and their important values were so low that they could not constitute a significant impact on native species. By the research it implied that different land use types seriously affected the species composition and species diversity of herb community. The herbaceous community changed with land use types variation,diversification of land use could contribute native herbaceous species diversity protection. Hence,to study on the herbaceous plant diversity of different land use patterns in rural environment is helpful for plant diversity conservation in rural area and pushing up beautiful China construction.
