Natural and artificial factors of grassland degradation in Maduo County in source region of Yellow River were analyzed in this paper. The results showed that overgrazing was the major reason for grassland degradation. Compared with historical average, annual temperature and precipitation in Maduo had an obvious rise since the end of 1980s. Temperature rise(More)
Urbanization involves the replacement of vegetated surfaces with impervious built surfaces, and it often results in an increase in the rate and volume of rainwater surface runoff. Urban green spaces play a positive role in rainwater-runoff reduction. However, few studies have explored the benefits of rainwater-runoff reduction by urban green spaces. Based(More)
In this article, the economic value of ecosystem services in Mangcuo Lake drainage basin was estimated with the table of equivalent weight factor of economic value of ecosystem services of China, and the economic value of food production per hectare was supplied by cropland ecosystem and land-use situation in 1990 and 2000. The results showed that the(More)
The current pressure on production resources of the People’s Republic of China, such as land and water to feed the growing population, necessitates the assessment of farming practices. This is particularly critical in the North China Plain, which is the food bowl of the country. This study assesses the economic, environmental and socio-institutional aspects(More)
Biodiversity maintenance and soil improvement are key sustainable forestry objectives. Research on the effects of bamboo forest management on plant diversity and soil properties are therefore necessary in bamboo-growing regions, such as southeastern China's Shunchang County, that have not been studied from this perspective. We analyzed the effects of(More)
In this study, Moderate Resolution Imaging Spectroradiometer (MODIS) data and the multiple linear regression model were used to estimate distribution of biomass resources in 2010. The establishment of models, developed using different vegetation biomass sample data, normalized difference vegetation index (NDVI), leaf area index (LAI), meteorological data,(More)
We investigated community structure and tree species diversity of six subtropical mountain forests in relation to 11 topographical and edaphic factors in Lower Lancang River Basin, Yunnan Province, China, based on a census of all trees with diameter at breast height≥5 cm in 45 0.06-ha plots. The forests were as follows: a river valley monsoon forest,(More)
Research on the spatial flow of ecosystem services can help to identify the spatial relationships between service-providing areas (SPAs) and service-benefitting areas (SBAs). In this study, we used the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model to stimulate the flow paths of the wind erosion prevented by ecosystems in(More)
China is facing severe acid deposition. Acid deposition can cause economic loss, corrosion, and damage to materials, and the reduction of material life span. In this study, the administrative areas (including municipalities, prefecture-level cities, regions, autonomous prefectures, and leagues—hereinafter referred to the cities) at and above the prefecture(More)
