Research on the Strategy for Improving Cultivated Land Quality in China

Hongqi Zhang, Minghong Tan, Xiangbin Kong, Yongmei Xu, Erqi Xu, Erping Shang

Strategic Study of CAE 2018, Volume 20, Issue 5,   Pages 16-22 doi: 10.15302/J-SSCAE-2018.05.003

Abstract:

Based on a systematic analysis of changes in quantity and quality of cultivated land in China, this paper put forward an overall strategic thinking of realizing three strategic transformations in the cultivated land management from the aspects of quantity, quality, and ecology of the cultivated land. Five important measures, including enhancing the cultivated land quantity in China, curbing undisciplined growth of construction land, improving the fertility of cultivated soil, preventing and controlling heavy metal pollution of soil, and preventing and controlling agricultural film pollution, were proposed. It was also recommended that four major projects, namely middle- and low-yield farmland reforms, comprehensive improvement of rural land, comprehensive reparation of heavy metal pollution of soil, and soil and water conservation, sand prevention, and saline soil improvement, should be implemented as soon as possible.

The effect of texture and irrigation on the soil moisture vertical-temporal variability in an urban artificial

Xiaofeng ZHANG,Xu ZHANG,Guanghe LI

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 2,   Pages 269-278 doi: 10.1007/s11783-014-0672-y

Abstract: Soil moisture variability in natural landscapes has been widely studied; however, less attention has been paid to its variability in the urban landscapes with respect to the possible influence of texture stratification and irrigation management. Therefore, a case study was carried out in the Beijing Olympic Forest Park to continuously monitor the soil in three typical profiles from 26 April to 11 November 2010. The texture stratification significantly affected the vertical distribution of moisture in the non-irrigated profile where moisture was mostly below field capacity. In the profile where irrigation was sufficient to maintain moisture above field capacity, gravity flow led to increased moisture with depth and thus eliminated the influence of texture. In the non-irrigated sites, the upper layer (above 80 cm) exhibited long-term moisture persistence with the time scale approximating the average rainfall interval. However, a coarse-textured layer weakened the influence of rainfall, and a fine-textured layer weakened the influence of evapotranspiration, both of which resulted in random noise-like moisture series in the deeper layers. At the irrigated site, frequent irrigation neutralized the influence of evapotranspiration in the upper layer (above 60 cm) and overshadowed the influence of rainfall in the deeper layer. As a result, the moisture level in the upper layer also behaved as a random noise-like series; whereas due to deep transpiration, the moisture of the deep layer had a persistence time-scale longer than a month, consistent with characteristic time-scales found for deep transpiration.

Climate change and China’s mega urban regions

Chaolin GU, Sunsheng HAN

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 4,   Pages 418-430 doi: 10.1007/s11709-010-0075-5

Abstract: China’s mega urban regions are focal points of economic development and environmental concerns. This paper positions four mega urban regions (i.e., the Yangtze River Delta, the Pearl River Delta, the Bohai Bay Area, and the South-eastern Fujian Province) along China’s coast into the national economy and elaborates their development challenges and planning innovations. Mega urban regions in China are spatial consequences of rapid economic transition. They deserve close scrutiny and demands for innovative planning responses in order to maintain their key role in driving economic growth but limiting their greenhouse gas emission.
