MAJOR PROBLEMS OF SUSTAINABLE DEVELOPMENT ALONG THE BANK AREA OF THE CHANGJIANG RIVER

Developing the Changjiang(Yangtze) River and building a developed economic zone along the bank area of the Chanajiang River is a great strategic decision of the national macroeconomic development distribution. This decision has both given an impetus to fast development of the regional economy and exacerbated the contradiction among economy and resources and environment. In this paper, some major problems ekisting in economic sustainable development, such as scattered industrial structure, duplicated construction of the great projects, enlarging the development gap of the regional economy and deteriorated environment etc., have been studied. The results show that scattered structure and duplicated distribution of some key industries and projects, especially automobile, electronics and petrochemical industry and communication, power installations, is one of the reasons for low industrial economic benefit; the great development gap among upper, middle and lower reaches areas are enlarging since the 1990’ s; soil erosion, nood disaster and environmental pollution are still exacerliating due to unreasonable over-development. Based on the above analysis, this paper brings out some countermeasures and proposals for increasing the ability of regional sustainable development, including transregional reorganization of industrial structure linking by assets and speeding the process of regional economy integration; gradually controlling and reducing the development gap arnong upper, middle and lower reaches areas through regional cooperation on a mutually beneficial basis; as well as strengthening ecological construction and environmental protection and increasing environmental bearing capacity etc.

Study on the Role of Tidal Currents in the Process of Formation and Development of the Changjiang River Delta

The Changjiang River Delta is a delta of tremendous scale which is formed under the control of tide and tidal currents. The study on the role of tide and tidal currents in the process of formation and development of the Changjiang River Delta can provide a typical example for the ocean-continent interaction process in the east area of our country. The tide and tidal currents in the Bohai Sea, Yellow Sea and East China Sea at the post-glacial transgression maximum are simulated, the sediment transport field in the Paleo-Changjiang River Estuary(PCRE) and its peripheral area at that time is calculated, and the seabed erosion/accretion pattern is obtained according to the divergence of sediment transport rate. The results show that a distinctive wave belly of standing tidal wave existed at the post-glacial transgression maximum and the wave belly lines protruded seawards from the wave belly point in the mouth of the PCRE. Under the wave belly control tidal currents converge to or diverge from the wave

Study on High Quality Development Strategy of the Yellow River Basin-Take Rural Development in Zhengzhou, China as an Example

High-quality development of the Yellow River Basin is a development strategy that China has been vigorously promoting in recent years,and it is also an important point to realize the goal of balanced regional development and the Chinese dream in the long term.In the context of the implementation of the strategy,Zhengzhou,as a major city in the central region where the Yellow River flows through,has a strong driving effect on the surrounding counties and cities.At the same time,Zhengzhou’s rural modernization process is gradually accelerated,and the poverty alleviation has achieved remarkable results.Therefore,this paper introduces the development background of the Yellow River Basin region,explores the significance of this strategy for the basin region,and takes the rural construction of Zhengzhou as an example to look into the future development path.

REGIONAL DIFFERENCES OF ECONOMIC DEVELOPMENT OF THE CHANGJIANG RIVER VALLEY

Unbalanced development in the Changjiang (Yangtze) River Valley is so obvious that it can be divided into three grades. The east including Shanghai municipality, Jiangsu and Zheyang provinces enjoys its advance prestige; the middle including Anhui, Jiangxi, Hubei, Hunan and Sichuan provinces occupies the second position; and the wet including Guizhou, Yunnan, Qinghai provinces and the Xizang (Tibet) Autonomous Region remains backward. The differences of the three grades are shown in the following aspects: (1) economic strength including gross national product (GNP), gross output value of industry and agriculture etc, inclines to the east; (2) the total social output valed per capita, the output value of agriculture and industry per capita are lowerand lower from the lower reaches to the upper arches; (3) the proportions of output value of industry to total output value of industry and agriculture, light industry to total industry, rural industry to agriculture, etc. are gradually reduced from the east to the west; (4) the ratio of farming labour employment to the total labour employment of society in the east is much lower than that of the middle and upper reaches; (5) the living standard in the lower reaches is much higher than that of the middle and upper reaches.

Hydraulic Energy Development of Changjiang Valley in First 5 Decades of 21st Century

The Changjiang River Valley is rich in hydraulic energy resources. A rough estimation of the technically developable volume and the economically developable volume for the Changjiang River Valley was drawn out on the basis of new data. According to the estimation, the developable water energy resources of the whole valley is 257 627.60 MW with an annual energy output of 1 195.142 billion kW·h - respectively amounting to 120.6% and 116.3% of the General Investigation result in 1980. The proportion of economically developable volume in the technically developable volume ranges the medium level in the world. According to the 3-step plan for the national economic and social development, the economic situation of our country will come up to the standard of medium-developed countries in the mid of the 21st century. Calculation reports from related departments show that the national electric power requirement in the Year 2050 will be 6 200 billion kW·h (basic scheme) ～11 600 billion kW·h (ideal scheme) while the electric power requirement of the South-west, Central and East areas of the nation within the Changjiang River Valley will amount to 44% ～ 50 %. In order to satisfy the electric power requirement of the national economic and social development, the development and utilization of the hydraulic energy in the Changjiang River Valley should be speeded up by stressing its strategic position and taking effective measures. The structure of the electric energy components of the three areas will be improved with the increasing proportion of the hydroelectricity. The hydroelectricity should be mainly developed in the South-west area; both the hydroelectric and fossil-fired power should be developed in the Central China; the fossil-fired power should be mainly developed in the combination of hydropower while nuclear power will be properly developed in the East China. In the Year 2050, the development of the economically developable hydraulic energy in the whole valley will be basically completed and the proportion of the hydropower in the electric energy components will be 40%.

梯级水电开发背景下的外来植物入侵状况与防控管理--以澜沧江流域(云南段)为例

梯级水电开发是一种有效的可再生能源生产方式,但梯级水电开发与外来生物入侵之间的关系尚未得到足够重视。本文基于对澜沧江流域(云南段)梯级水电开发区的野外实地调查和数据搜集整理,查明了区域的外来入侵植物种类和分布状况,初步分析和探讨了梯级水电开发与外来植物入侵之间的相互关系。研究结果显示,澜沧江流域(云南段)共发现外来入侵植物202种,隶属51科和146属,其中来源于美洲的植物最多(126种,52.07%),草本入侵植物(71.78%)占主导,且大多入侵植物通过有意引入(76.23%)而来。风险评估显示,菊科、豆科和大戟科的植物对生态影响最为显著。在空间分布上,入侵植物的富集区域和生态危害严重区与水电开发区高度重合。现有证据尚不能证明水电开发直接导致了新入侵植物的增加,但确实在一定程度上促进了外来入侵植物在区域内的引入与扩散。同时,本文还针对性地提出了水电开发建设与运行中防控外来入侵植物的具体建议。

长江经济带发展战略对工业企业绿色转型的影响研究

目前,我国已进入产业转型升级的重要战略机遇期,绿色转型是工业企业普遍面临的重大现实挑战。以2008-2021年A股上市的工业企业为样本,运用双重差分模型分析长江经济带发展战略对工业企业绿色转型的影响及其作用机制。研究发现:长江经济带发展战略显著地促进了长江经济带工业企业绿色转型,经过一系列稳健性检验后上述结论依然成立;机制分析表明,长江经济带发展战略通过推动企业绿色技术创新、加快区域经济集聚以及提高政府环境规制执行效率促进工业企业绿色转型;异质性分析表明,内部控制质量较差、成立时间较早以及亏损较为严重的企业,其绿色转型进程受长江经济带发展战略的推动作用更为显著,经济发展水平较低、工业化进程较慢以及非沿江地区的工业企业亦是如此。未来应加强区域发展战略对工业企业绿色转型的正向影响,建立均衡的长江经济带发展战略作用机制,实现工业企业绿色转型方式多样化。
