To understand the relationship between plant community succession and soil nutrient dynamics is crucial in intervening vegetation succession. This paper reported the results from a study carried out in a forest-steppe zone on the Loess Plateau, with emphasis on the vegetation characteristics and soil nutrient dynamics duringvegetation restoration on(More)
The prediction and mapping of potential vegetation distribution is of instructive to the ecological restoration planning. By using generalized additive model (GAM) and in combining with GIS spatial analyst and environmental stratification sampling techniques, a distribution model for 24 dominant species in Yanhe River catchment was developed, and, based on(More)
Increasing evidence indicates that current dynamic global vegetation models (DGVMs) have suffered from insufficient realism and are difficult to improve, particularly because they are built on plant functional type (PFT) schemes. Therefore, new approaches, such as plant trait-based methods, are urgently needed to replace PFT schemes when predicting the(More)
The relationship between vegetation and soil moisture deserves attention due to its scientific importance and practical applications. However, the effects of soil moisture on vegetation development and succession are poorly documented. Here we study soil water storage in Yanhe watershed at northern Shaanxi on five different land uses, namely shrubland,(More)
Soil carbon sequestration is an ecosystem process that can provide important ecosystem services such as climate regulation and mitigation of global warming. Spatiotemporal variation in the soil organic carbon (SOC) stock is the basic information needed for landscape management and determination of regional carbon budgets. The objective of this study was to(More)
A risk assessment of vegetation zone responses to climate change was conducted using the classical Holdridge life zone model on the Loess Plateau of Northwest China. The results show that there are currently ten vegetation zones occurring on the Loess Plateau (1950–2000), including alvar desert, alpine wet tundra, alpine rain tundra, boreal moist forest,(More)
Soil fertility is important factors for growth and productivity of vegetation. The relationship between vegetation and soil fertility deserves attention due to its scientific importance and practical applications. However, the effects of soil fertility on vegetation development and succession are poorly documented. Here we study soil fertility in Yanhe(More)
This article selected zonal plant communities as the research objects in different vegetation zones in Yanhe River basin. We measured six leaf traits of the dominant species and main accompanying species in each community, and then analyzed the relationships and their changes along with environmental gradients between these traits in order to understand the(More)
Evaluating the sustainability of cropland use is essential for guaranteeing a secure food supply and accomplishing agriculture sustainable development. This study was conducted in the ecologically vulnerable Loess Plateau region of China to evaluate the sustainability of cropland use based on an ecological footprint model that integrates emergy analysis.(More)
The paper focused on Artemisia sacrorum in the stable natural plant community in three vegetation zones (forest, forest steppe and steppe) in the Yanhe River catchment. The following plant functional traits were measured at each sample site, i.e., specific leaf area (SLA), leaf tissue density (LTD), leaf nitrogen concentration (LNC), leaf phosphorus(More)
