Research on Optimizing the Construction of the Long March National Cultural Park from the Perspective of Cultural Route Heritage Protection

The idea of cultural route heritage protection expands the protection theory for world cultural heritage.The Long March route carries the prominent characteristic of cultural route heritage.By actively building the Long March National Cultural Park,China has strengthened the overall protection and integrated utilization of the Long March cultural heritage,upgraded the hardware facilities for exhibition,and investigated ways to protect cultural route heritage with Chinese characteristics.During the construction of the Park,it is necessary to draw on the concept and norms of the cultural route heritage protection,optimize the construction approach,and make the construction of the Park more in line with the linear cultural characteristics of Long March heritage.Specifically,it is proposed to improve the Long March cultural route heritage protection system oriented towards“authenticity”protection,to deeply tap and interpret the prominent universal worth of the Long March route,augmenting the international dissemination of the Long March culture in an innovative way,and realizing a more scientific and effective protection and utilization of Long March cultural resources.

An Analysis of the Festivals and Holidays Celebrated by the Red Army During the Long March

The Long March of the Chinese Workers’and Peasants’Red Army is hailed as the“Red Ribbon on the Earth.”The Long March was characterized by revolutionary heroism and,at the same time,was no lack of revolutionary romanticism.This arduous journey also presented two difficult questions:whether to celebrate festivals and holidays or not and whether to celebrate them simply or grandly.By exploring such trade-offs,we can appreciate a strong sense of national identity among the Red Army soldiers as idealists,grasp more historical details of the world-shattering Long March,and feel the resilience and greatness of the Chinese nation.

On the connotation, challenge and significance of China’s “energy independence” strategy

The world’s energy is in the "third major transformation period" from fossil energy to new energy, and all countries in the world have formulated energy development strategies. Through advanced deployment, the United States is about to achieve "energy independence" relying on "unconventional oil and gas revolution". China’s energy development is faced with four challenges:(1) The population base and economic development scale determine the "totally huge amount" of energy consumption;(2) the "coal rich but oil and gas insufficient" resource structure determines the "unclean" energy consuming structure;(3) the increasing dependence on imported oil and gas determines the "unsafe" energy supply;and(4) the unconventional oil and gas endowment makes it impossible to achieve energy independence by copying the American model. From the perspective of the world energy trend and the unique situation of China’s energy, we put forward a "three-step" strategy for China to achieve "energy independence": From 2020 to 2035, "energy supply security" will be addressed by "cleaning coal, stabilizing oil and gas production and vigorously developing new alternative energy";from 2035 to 2050, the vision of "production independence" will be realized by relying on "domestic production and overseas oil and gas mining rights";from 2050 to 2100, "intelligent energy and new energy" will help China realize "energy independence". The two important signs of China’s "energy independence" are that domestic production accounts for more than 90% of the domestic consumption and clean energy production accounts for more than 70%, and energy security realizes "independence and self-control" and "long-term security". The strategic significance of "energy independence" is to ensure national energy security, drive the development of relevant major industries, achieve energy management reform, and implement the environmental protection goal of zero carbon emissions. The "energy independence" of China is a strategic mission, it might be fulfilled in the future with the growth of the state’s power, even when the domestic energy production does not catch up with the domestic consumption. Perhaps the world’s new technological revolution will exceed expectations, and China’s "energy independence" dream will eventually come true.

Effects of Aluminum Toxicity Induced by Acid Deposition on Pine Forest Ecosystem in Longli of Guizhou Province, Southwestern China

The effects of acid deposition on pine forest ecosystems in Longli of Guizhou Province, southwestern China are studied using indoor experiments and model simulations. Indoor experiments are designed to explore the aluminum toxicity on pine seedlings, and the long-term soil acidification model(LTSAM) and a terrestrial biogeochemistry model(CENTURY) are used to simulate the influences of acid deposition on pine forest ecosystems. The indoor experiment results of aluminum toxicity show that aluminum ions in solution limit plant growth and acid deposition enhances this effect by facilitating the release of aluminum ions from the soil. Pine seedling biomass and root elongation decrease as the aluminum concentration increases. The results of model simulations show that the soil chemistry varies significantly with different changes in acid deposition. When the acid deposition increases, the pH value in the soil solution decreases and the soil Al^(3+) concentration increases. The increased acid deposition also has negative impacts on the forest ecosystem, i.e., decreases plant biomass, net primary productivity(NPP) and net CO_2 uptake. As a result, the soil organic carbon(SOC) decreases because of the limited supply of decomposition material. Thus acid deposition need be reduced to help protect the forest ecosystems.
