“…Classic studies include the effects of drought on the collapse of various Asian civilizations during the early and middle Holocene (Rothman, 2001;Weiss, 2000), the effects of increasing drought incidence and severity on societies in central and southwest North America during the last two millennia (Jones et al, 1999;Haug et al, 2003), and the global effects of generally cooler, more variable climates during the Little Ice Age beginning about A.D. 1350 (Grove, 1988;Fagan, 2000). Sea-level changes have also influenced prehistoric cultural evolution, both by periodically drowning areas valued by humans, as in eastern China (Zhang et al, 2005), and by radically altering the nature and degree of productivity of nearshore ecosystems thereby impacting the lifestyles of dependent humans, as in many Pacific Islands (Esaka, 1943;Amesbury, 1999). All such studies, fuelled by an increase in the amount and precision of relevant paleoclimate information in various parts of the world, is leading to a revival of the idea of environmental determinism.…”

Pollen, plant seeds and phytoliths from an AMS dated sediment profile at the Xishanping site indicate that the cultivation of rice might start no later than 5070 cal. a BP in the region of Tianshui, Gansu Province. It continued from 5070 to 4300 cal. a BP. This is so far the oldest and the most northwestern record of cultivated rice in Neolithic China, which extends the known region of prehistoric rice cultivation at least 2° longitude to the west. This finding provides important evidence for reconstructing the cultivation region of rice at 5000 a BP (an important time period), and its spreading history in East Asia, during the Neolithic.archaeobiological record, northwestern China, Xishanping site, cultivated rice, 5000 years

“…Additionally, economic development, population growth, and urban expansion, especially the development of the Shengli oilfield, caused a number of wetlands to be destroyed by the building of roads, dams, ports, and other infrastructure [7,8,22,75,76]. The integrity of the wetlands has been undermined due to the infrastructure construction and the original wetland landscape has become increasingly degraded and fragmented.…”

Yellow River Delta wetlands are essential for the migration of endangered birds and breeding. The wetlands, however, have been severely damaged during recent decades, partly due to the lack of wetland ecosystem protection by authorities. To have a better historical understanding of the spatio-temporal dynamics of the wetlands, this study aims to map and characterize patterns of the loss and degradation of wetlands in the Yellow River Delta using a time series of remotely sensed images (at nine points in time) based on object-based image analysis and knowledge transfer learning technology. Spatio-temporal analysis was conducted to document the long-term changes taking place in different wetlands over the four decades. The results showed that the Yellow River Delta wetlands have experienced significant changes between 1973 and 2013. The total area of wetlands has been reduced by 683.12 km 2 during the overall period and the trend of loss continues. However, the rates and trends of change for the different types of wetlands were not the same. The natural wetlands showed a statistically significant decrease in area during the overall period (36.04 km 2 ·year −1 ). Meanwhile, the artificial wetlands had the opposite trend and showed a statistically significant increase in area during the past four decades (18.96 km 2 ·year −1 ). According to the change characteristics revealed by the time series wetland classification maps, the evolution process of the Yellow River Delta wetlands could be divided into three stages: (1) From 1973From -1984, basically stable, but with little increase; (2) from 1984-1995, rapid loss; and (3) from 1995-2013, slow loss. The area of the wetlands reached a low point around 1995, and then with a little improvement, the regional wetlands entered a slow loss stage. It is believed that interference by human activities (e.g., urban construction, cropland creation, and oil exploitation) was the main reason for wetland degradation in the Yellow River Delta over the past four decades. Climate change also has long-term impacts on regional wetlands. In addition, due to the special geographical environment, the hydrological and sediment conditions and the location of the Yellow River mouth also have a significant influence on the evolution process of the wetlands.
