Asarum longirhizomatosum, originally described from Guanxi Province in China by C. F. Liang and C. S. Yang in 1975, was invalidly published in the original publication, because two collections were cited as type. The name is validated here by designating the collection Chao-Liang Zhang 002 (IBK 00190377) as the holotype. Source

In Flora Reipublicae Popularis Sinicae and Flora of China, the reference citations of Myristica yunnanensis and Cyclobalanopsis yonganensis are incorrect. The publication date of Myristica yunnanensis is 1977, not 1976, and that of Cyclobalanopsis yonganensis is 1999, not 1993. Additionally, the authorship of the combination C. yonganensis belongs to C. C. Huang, Y. T. Zhang and B. Bartholomew, but not to Y. C. Hsu and H. W. Jen. To formalize the usage of the two names, they are revised here. © 2011 Bangladesh Association of Plant Taxonomists. Source

According to the data source used, the major methods globally used to estimate forest above-ground biomass were introduced in this paper. The methods can be categorized into forest inventory data based method and remote sensing based method. Based on previous studies conducted in China and abroad, we summarized the characteristics and the deficiencies of these two kinds of methods and then preliminarily explored the synergetic method in estimating forest aboveground biomass using multi-source data. In accordance with the deficiencies of estimation methods, some discussions about the scale, parameterization and validation of the models were given and some work concerning the estimation of forest aboveground biomass in the future was stressed.

Forests play an important role in acting as a carbon sink of terrestrial ecosystem. Although global forests have huge carbon carrying capacity (CCC) and carbon sequestration potential (CSP), there were few quantification reports on Chinese forests. We collected and compiled a forest biomass dataset of China, a total of 5841 sites, based on forest inventory and literature search results. From the dataset we extracted 338 sites with forests aged over 80 years, a threshold for defining mature forest, to establish the mature forest biomass dataset. After analyzing the spatial pattern of the carbon density of Chinese mature forests and its controlling factors, we used carbon density of mature forests as the reference level, and conservatively estimated the CCC of the forests in China by interpolation methods of Regression Kriging, Inverse Distance Weighted and Partial Thin Plate Smoothing Spline. Combining with the sixth National Forest Resources Inventory, we also estimated the forest CSP. The results revealed positive relationships between carbon density of mature forests and temperature, precipitation and stand age, and the horizontal and elevational patterns of carbon density of mature forests can be well predicted by temperature and precipitation. The total CCC and CSP of the existing forests are 19.87 and 13.86 Pg C, respectively. Subtropical forests would have more CCC and CSP than other biomes. Consequently, relying on forests to uptake carbon by decreasing disturbance on forests would be an alternative approach for mitigating greenhouse gas concentration effects besides afforestation and reforestation. © 2014, The Author(s).
