The Loess Plateau is the core area in the Yellow River basin for implementing environmental protection and high-quality development strategies. A series of ecological projects has implemented aimed at soil and water conservation and ecological management on the Loess Plateau over the past 70 years. The effects of the ecological projects are apparent mainly through a marked increase in vegetation cover, controlled soil erosion and reduced flow of sediment into the Yellow River, continual optimization of the industrial structure and increased production from arable land, poverty alleviation and greater prosperity, and optimal allocation of space for biological organisms. Major problems have also been analyzed in ecological management including the fragile ecosystem of the region, maintaining the stability of vegetation, lower agricultural productivity and continued risk from natural disasters. Some suitable schemes and models have been developed for the coordinated development of the region through research and demonstration, striking the optimum balance between rural industry and ecology, and increased regional capacity to supply high-quality ecological products. Countermeasures to address the problems are suggested to guide ecological management and high-quality development in the future.

TRANSFORMATION OF AGRICULTURE ON THE LOESS PLATEAU OF CHINA TOWARD GREEN DEVELOPMENT

Loess Plateau of China is a typical dryland agricultural area. Agriculture there has transformed from food shortage toward green development over the past seven decades, and has achieved world-renowned achievements. During 1950–1980, the population increased from 42 to 77 million, increasing grain production to meet food demand of rapid population growth was the greatest challenge. Engineering measures such as terracing and check-dam were the crucial strategies to increase crop production. From 1981 to 2000, most of agronomic measures played a key role in increasing crops yield, and a series of policy support has benefited millions of smallholders. As expected, these measures and policies greatly increased crop production and basically achieved food security; but, low per capita GDP (only about 620 USD in 2000) was still a big challenge. During 2001–2015, the increase in agricultural and non-agricultural income together supported the increase in farmer income to 5781 USD·yr–1. Intensive agriculture that relies heavily on chemicals increased crop productivity by 56%. Steadfast policy support such as “Grain for Green Program” had an overwhelming advantage in protecting the natural ecological environment. In the new era, the integration of science and technology innovations, policy support and positive societal factors will be the golden key to further improve food production, protect environment, and increase smallholder income.

总结了城市可持续发展面临着占地多、交通堵、停车难、步行难、能耗高、效率低、治安差、不宜居及交通事故频发、交通投资巨大等十大难题,给出了破解这些难题的基本公式;在各项基本公式的指引下,由诸多复杂的城市模式方案中升华而产生的节约·生态·畅通城市新模式(JD模式)一旦得到推广,十大难题将全面破解,城市宜居指数将提高1倍;可持续发展的城市格局不应该像象棋棋盘一样锁定中心位置,而应该像围棋棋盘一样各个中心的位置可以在发展中形成和变化,这就是城市泛中心论。

最近半个世纪,青藏高原地面气候发生了一定变化,主要表现在地面平均气温明显上升,冬季、夜间和城镇区域气温上升尤其显著,多数地区降水量呈现不同程度增加。气候变暖对高原地区自然和人类系统产生了一定影响。预计未来青藏高原气候总体将继续趋向变暖,这可能对冰冻圈、河湖系统、陆地植被、农业自然条件、能源气候资源、交通和水利设施、城镇人居环境等产生明显影响。与生态保护和经济社会发展有关的各类大型工程的规划、设计和维护,需要考虑今后气候变化的可能影响,及早制定可行的适应性措施。
