Environment without light sources was taken as the control group. The results showed that different light sources and different distances from light sources to plants had diversified impact on the photosynthetic physiology of Picea koraiensis. Among these different color lights, green light had the least influence on Picea koraiensis, yellow light and purple light had greater influence.展开更多

During the Western Han Dynasty, after a passage way to the Western regions was "hollowed out" and secured, commerce and trade along the route boomed, people started to form clusters, and towns and cities were established. Since the late Tang Dynasty, under the combined effects of natural disasters and manmade misfortunes, regions along the Silk Road in Northwest China were severely depopulated, the towns and cities declined, the ecological environment became fragile, and the social space in West China shrank dramatically. The West Development Strategy later launched by the People' s Republic of China had its focus on optimization and reconstruction of domestic social space, whereas the Belt and Road Initiative(referring respectively to "the Silk Road Economic Belt", hereinafter "the Belt", and "the 21 st-Century Maritime Silk Road", " the Road") is rooted in the planning of space for long-term development and production. In building the Belt and Road, we should take the initiative and necessary steps to manage sound top-level designs; further break down the space alienation emanating from the domestic administrative divisions, and stick to the policy of all around opening up; base the endeavor on the new types of urbanization and strengthen social construction to optimize spatial structures; pay attention to the leading role of space consumption by vigorously developing Silk Road tourism; enhance the transportation and communication infrastructure in the node cities to achieve seamless docking and deep-level integration of both social space and natural space along the Belt and Road.展开更多
