AbstractHuman activity has eliminated many of the natural lowland ecosystems of the Middle and Lower Yellow River Valley, and has modified the rest, making it difficult to understand what species are native to the region. As a step towards the reconstruction of these lost environments, this paper employs zooarchaeological and other evidence to identify the native mammals of the region. We provide basic ecological information about these animals and discuss controversial or difficult cases in more depth. Our goal is not only to study China's environmental history, but also to make clear that conventional understandings of species ranges are based on the distributions of animals in the modern period, when many had already been eliminated from large areas by human activity.

Use Efficiency

AbstractThe cotton-wheat double-cropping system is widely used in the Yellow River Valley of China, but whether and how different planting patterns within cotton-wheat double-cropping systems impact heat and light use efficiency have not been well documented. A field experiment investigated the effects of the cropping system on crop productivity and the capture and use efficiency of heat and light in two fields differing in soil fertility. Three planting patterns, namely cotton intercropped with wheat (CIW), cotton directly seeded after wheat (CDW), and cotton transplanted after wheat (CTW), as well as one cotton monoculture (CM) system were used. Cotton-wheat double cropping significantly increased crop productivity and land equivalent ratios relative to the CM system in both fields. As a result of increased growing degree days (GDD), intercepted photosynthetically active radiation (IPAR), and photothermal product (PTP), the capture of light and heat in the double-cropping systems was compared with that in the CM system in both fields. With improved resource capture, the double-cropping systems exhibited a higher light and heat use efficiency according to thermal product efficiency, solar energy use efficiency (Eu), radiation use efficiency (RUE), and PTP use efficiency (PTPU). The cotton lint yield and biomass were not significantly correlated with RUE across cropping patterns, indicating that RUE does not limit cotton production. Among the double-cropping treatments, CDW had the lowest GDD, IPAR, and PTP values but the highest heat and light resource use efficiency and highest overall resource use efficiency. This good performance was even more obvious in the high-fertility field. Therefore, we encourage the expanded use of CDW in the Yellow River Valley, especially in fields with high fertility, given the high productivity and resource use efficiency of this system. Moreover, the use of agronomic practices involving a reasonably close planting density, optimized irrigation and nutrient supply, and the application of new short-season varieties of cotton or wheat can potentially enhance CDW crop yields and productivity.

Ancient Silk Road

Known as “the Millennium Town beside the Yellow River” Qingcheng Town in Yuzhong County has many rich cultural heritages and profound cultural foundation. Its terrain belongs to the typical Yellow River Valley. It was an important traffic wharf of the ancient Silk Road, and a terminal frontier military center from Tang Dynasty to Ming Dynasty. By researching and analyzing the Qingcheng town, the thesis summarizes its characteristics of the spatial layout and ecological culture.

Abstract This article attempts to cast doubt on prior scholarship regarding Maoist environmental rhetoric regarding forestry, which has tended to characterize it as destructive, militaristic, and irrationally extractive. Against this simplistic portrayal of Maoist rhetoric concerning Chinese forestry and Mao Zedong’s attitudes toward nature, this article demonstrates that the rhetoric of forestry and environment in general during Mao’s period is scientific, rational, and even constructive regarding tree planting. To demonstrate the rational and premeditated aspect of socialist forestry and environmental history, the article first explores the speeches and writings of Japan and Germany educated Liang Xi, probably the most important forester in early socialist China, who advocated tree planting as a way of tackling the problem of the scarcity of trees. During the early 1950s, his firm belief that tree planting could solve the problems of the Yellow River clashed with hydrologists who also aspired to solve China’s environmental challenges. Using newspaper reports from the People’s Daily, the article then examines the rhetoric of the “Greening the Motherland” campaign launched by Mao in 1956. During this campaign, Mao pushed the Yellow River’s tree-planting initiative to a national scale, thanks largely to the foresters’ concerted efforts of persuasion. This nationwide campaign, in concert with the new regime's state-building efforts, required foresters to instill knowledge of tree planting in a broad range of people at the grassroots level as well as to strategically integrate it within the socialist revolutionary and global environmental discourse.
