“…However, there are numerous exceptions to this trend, and numerous potential mechanisms generating the various diversityproductivity relationships seen (Morin 2011). As a further complication, urbanization can decrease (Milesi et al 2003;Xu et al 2007) or increase net primary productivity (Buyantuyev and Wu 2009), with different trends possible at different spatial scales (Imhoff et al 2004). A boost in urban diversity is typically attributed to the presence of nonnative, often invasive, species, and often at the expense of natives (Pyšek et al 2004).…”

“…For instance, Lu et al concluded that NPP had a significant negative correlation with population density, gross domestic product (GDP) and residential location in Southeastern China [35]. Xu et al analyzed the impact of urbanization on NPP in Jiangyin County, China, and the results showed that land cover changes triggered by urbanization reduced NPP directly [36]. Vegetation decrease triggered by land-cover changing to an impervious surface in urban areas can result in environmental threats with NPP reduction and surface temperature variation.…”

Vegetation is one of the most important components of the terrestrial ecosystem and, thus, monitoring the spatial and temporal dynamics of vegetation has become the key to exploring the basic process of the terrestrial ecosystem. Vegetation change studies have focused on the relationship between climatic factors and vegetation dynamics. However, correlations among the climatic factors always disturb the results. In addition, the impact of anthropogenic activities on vegetation dynamics was indeterminate. Here, vegetation dynamics in 14 provinces in Eastern China over a 10-year period was quantified to determine the driving mechanisms relating to climate and anthropogenic factors using partial correlation analysis. The results showed that from 1999 to 2008, the vegetation density increased in the whole, with spatial variations. The vegetation improvement was concentrated in the Yangtze River Delta, with the vegetation degradation concentrated in the other developed areas, such as Beijing-Tianjin-Hebei Region and the Pearl River Delta. The annual NDVI changes were mainly driven by temperature in Northeast China and the Pearl River Delta, and by precipitation in the Bohai Rim; while in the Yangtze River Delta, the driving forces of temperature and precipitation almost equaled each other. Furthermore, the impact of anthropogenic activities on vegetation dynamics had accumulative effects in the time series, and had a phase effect on the vegetation change trend.

“…The work of many investigators has shown that LUCC affects the global system in various ways, including atmospheric composition, regional climate, soil quality, hydrology, and biodiversity (Xu et al, 2007;Turner et al, 2007). Humans are the main force behind the global conversion of land cover (Kuemmerle et al, 2006), and their ecological and environmental influence has been steadily increasing.…”

Land Cover Changes in Northeast China From the Late 1970s to 2004

Abstract. This paper presents a quantitative analysis of land cover changes in northeast China from the late 1970s to 2004 using remote sensing and the Geographic Information System. Land covers are mapped into six classes and nine sub-classes from multi-temporal Landsat MSS, TM and ETM+ images and SRTM DEM data. It is found that while forestland and wetland were greatly reduced until 2000 due to farming expansion and urbanization, spurred by population growth, their decline trends have been revered most recently. Meanwhile, built-up land has kept increasing. Further, the land cover changes occurred primarily in areas with low elevation and gentle slope. These results suggest that the forest and wetland protection and restoration projects have taken effect. However, there remains a long way to go before the ecosystems are greatly recovered and can function in the way that society expects.
