Multicropping Pattern Reveals Human Adaptation at the Wanbei Site (ca. 5.7–4.4 ka cal. BP) in the Middle and Lower Huai River Valley, China

Long term effects of climate on human adaptation in the middle Gila River Valley, Arizona, America

The Hohokam, an irrigation-based society in the American South West, used the river valleys of the Salt and Gila Rivers between 500 and 1500 AD to grow their crops. Such irrigated crops are linking human agency, water sources and the general natural environment. In order to grow crops, water available through rain and river flows needs to be diverted to land where the plants are grown. With a f...

Analysis of land use dynamics and landscape pattern change in the Huai river basin, China

This study presented the analyses of temporal and spatial change of land use dynamics and landscape pattern in the Huai river basin during the period 1986-2005 by using the land use dynamic degree model, the land use centroids and the landscape metrics; and discussed the driving forces of land use change over the period employed the gray relational analysis method. The main results showed that:...

Detection and Modeling of Vegetation Phenology Spatiotemporal Characteristics in the Middle Part of the Huai River Region in China

Vegetation plays an important role in atmospheric, hydrologic and biochemical cycles and is an important indicator of the impact of climate and human factors on the environment. In this paper, a method, which combines the empirical orthogonal function (EOF) and temporal unmixing analysis (TUA) methods, is applied to monitor the phenological characteristcs and spatial distribution of vegetation ...
