The traditional data envelopment analysis (DEA), bootstrap-DEA and Malmquist models are employed to measure different tourism efficiencies and their spatial characteristics of 61 cities in six coastal urban agglomerations in eastern China since 2000

In the catchment of South Luohe River, in the transitional zone between south and north China, 40 surface samples under 10 vegetation types were collected to reveal the relationship between pollen assemblages and vegetation. The results show

-year (1991–2005) fertilization sites of northern China. Six treatments were examined. It is highlighted that soil organic matter was significantly higher under P than under no-P fertilization. Soil organic matter accumulation significantly positively
correlated with Olsen P. The combination of chemical P and manure P with organic C input is a better strategy to increase soil Olsen P and SOC accumulation on farmland with maize–wheat rotation in northern China.
