Wetland changes in Jianghan Plain and simulation with GIS
Thiss paper describes how to combine GIS with geo-informatics and geography to simulate the wetland changes happened in Jianghan Plain in the middle reaches of the Yantze River in the last 40 years, and present the results. The environmental
implications of the wetland changes are discussed.

In this paper, the AA. use a long-term leaf area index data (LAI) to identify where changes happened and where has experienced the strongest change around the globe during 1981–2006. Results show that, over the past 26 years, LAI has generally
This paper includes regional dynamic change and the State regional development policy. Behind the practice of regional development is disputation on the developmental theories. It also outlines theories which guides the practice of China's regional

Late Pleistocene temperature depression and vegetation change in Ecuadorian Amazonia
The data of forest community change, from sites lying within the postulated glacial rain forest Napo refugium, provide the strongest paleoecological refutation of the refugial hypothesis yet obtained. The large temperature depression at 30,000 yr B
Spatial-temporal changes of Tianjin urban spatial morphology from 1978 to 2004
Taken fractal dimension, compact ratio, urban centroid and urban principal axis as the urban spatial characteristic indices, Tianjin city's urban area is investigated in the last 26 years in a quantitative perspective, and its traits and changes
Environmental change in the Yangtze river delta since 12,000 years B.P.
The AA. present a radiocarbon-dated pollen and sediment stratigraphy from a 52-m core collected from the Yangtze River delta. The data are interpreted in the context of climatic and vegetational changes, delta development, and sea-level history
Regional disparity in the changes of agricultural land use intensity in China during 1980-2002
Based on the cost-benefit data (1980-2002) of farm products and China Agriculture Yearbooks, this paper studies the regional disparity in the changes of the agricultural land use in China from 3 aspects such as the degree of intensity, the sown area
Late Quaternary paleoenvironmental changes in East Africa : a review of multiproxy evidence from palynology, lake sediments, and associated records

Radiative forcing over China due to albedo change caused by land cover change during 1990–2010
In this paper, high spatial and temporal resolution satellite products were used to analyze the driving mechanism for surface albedo change caused by land cover change during 1990–2010. In addition, the annual-scale radiative forcing caused
by surface albedo changes in China's 50 ecological regions were calculated to reveal the biophysical mechanisms of land cover change affecting climate change at regional scale. The results showed that the national land cover changes were mainly caused by land
reclamation, grassland desertification and urbanization in past 20 years, which were almost induced by anthropogenic activities. The mean radiative forcing caused by land cover changes during 1990–2010 in China indicates a warming climate effect.
