- Abstract:
-
In order to study which measure of ecological restoration is better for vegetation restoration in the hilly and gully area of Loess Plateau, the Danangou Catchment was selected as study area. Based on traditional vegetation investigation, the effects of ecological restoration on species diversity of herb plant community were discussed on aspect of measures and time of land use conversion. The results showed that: (1) within 30 years after the farmland abandonment, the richness index, the Simpson index, the Shannon-Wiener index and the evenness index increased over the time. Furthermore, the indices increased slowly in early period but increased at a high rate in later period; (2) the measures of ecological restoration had significant influence on the diversity of species in herb community, on the aspect of richness index, the value in abandoned farmland (converted from traditional farmland 23.875) is significantly higher than that in forestland (14.606) and shrubland (14.556). The Simpson index and the Shannon-Wiener index in abandoned farmland (0.945, 3.048) and forestland (0.931, 2.992) were significantly higher than that in shrubland (0.912, 2.563). Compared with shrubland and forestland (all converted from traditional farmland), abandoned farmland has more positive effects on the species diversity of herb community.
