Study on Sonneratia apetala productivity in restored forests in Leizhou Peninsula, China

The exotic Sonneratia apetala in Leizhou Peninsula, has shown outstanding fast-growing ability in restored mangrove forests, at the middle and high tide intertidal zone, with year-round fresh water input from drainage. By setting plot and selecting standard tree, investigation and measurement on height growth, diameter growth, biomass, productivity, and so on, were made in a S. apetala plantation at age of six at Lanbei, Fucheng, Leizhou Peninsula in May 2001. The investigating results showed that the mean annual height growth of plantation was 2.03 m and mean annual growth of diameter at breast height (DBH) was 2.35 cm. There exists a significant correlation between the diameter at ground surface (DGS) and DBH. The average biomass of a single standard tree in dry weight was 95.647 kg/m2. A ratio of above-ground biomass to under-ground biomass was 1.60. The stand biomass of unit area was 22.955 kg/m2, singletree wood volume was 88.23 dm3, and the annual wood volume productivity (PA) of the same year was 0.407. The forest energy accumulation was 424.851 MJ/m2, with annual solar energy fixing rate of 40.68 ×10-7%. It is concluded that S. apetala species had characteristics of outstanding high biomass accumulation and could be used as coastal planting tree species in southern China.

SCISSORS DIFFERENCE AND ITS IMPACTS ON ECONOMIC VALUE OF CULTIVATED LAND IN CHINA

The problem of price scissors difference between industrial products and agricultural products is one of the important problems in China. It impacts not only the living standard improvement of farmers but also the economic value of cultivated land, furthermore results in the direct and indirect loss of cultivated land resources. China＇s cultivated land area has decreased dramatically in recent years. An important reason for the decrease is the relatively low cost of cultivated land occupancy, which results from the distortion of economic value of cultivated land due to the existence of scissors difference. This study firstly analyzed the dynamic change of scissors difference and calculated the absolute and relative magnitude of scissors difference from 1997 to 2002, then computed the economic value of cultivated land before and after scissors difference adjustment in 2002, and finally discussed the inverted scissors difference. Results suggest that the scissors difference has a remarkable impact on the economic value of cultivated land, and the adjustment of scissors difference even inverted scissors difference to the economic value of cultivated land is indisoensable.

nSrDNA Appraisal of High Yield Flocculant Compound Bacteria and Their Application Effect

High effect flocculant compound bacteria were screened out with the product bacteria of flocculant in soil. Their system appraising study shows that two were actionomyces and the other was microzyme among the three bacteria. According to nSrDNA, the three bacteria were marked at a molecule level and the system growth tree was established, ensuring the position of compound bacteria at the molecule level. The purificant which was made of the compound bacteria has spreading value because of its excellent clearing effect for organic and inorganic polluted water.

滇中城市经济圈可持续发展探讨——基于P-E-R区域匹配模型

承载力分析是对社会可持续发展能力评价的有效指标,朱宝树教授提出的P-E-R区域匹配模型通过相对经济承载力和相对资源承载力的分析可具体考察各区域内人口与经济、资源承载力3者的关系,进而阐释区域社会可持续发展的能力。滇中城市经济圈各地相对经济承载力和相对资源承载力各有不同,因而所存在的可持续发展问题各异。影响滇中城市经济圈可持续发展的问题主要是人口压力大、资源环境承载力脆弱、经济发展滞后、产业支撑力不够等。因此,针对这些影响滇中城市经济圈可持续发展的问题,制定一些合理的相关人口政策和经济政策对滇中城市经济圈的可持续发展是有必要的。

Ecological Security Assessment in County Area Based on P-S-R Model——A Case Study of Ningwu County,Shanxi Province

To further understand the status quo and change tendency of ecological security in county area, we took the example of Ningwu County, the headstream of Fenhe River, confronting serious eco-environment problem and considerable human impacts. Taking Ningwu as the study area and using variation coefficient method to determine the weights of the indices, we built ecological security pattern based on Pressure-State-Response （P-S-R） Model of Organization for Economic Cooperation and Development. The ecological security status was evaluated by calculating eco-security index （ESI） with socio-economic statistical data of Ningwu during 2001 -2010. The results showed that the situation of eco-security had been improved from heavy alarm to relative safety during 2001 -2010. It reflected that the ecological economic system in Ningwu County tended to be relaxed constantly after experienced a sharp conflict between ecological environment and economic growth. The ecological safety awareness was growing, however, by force of the objective requirements of population growth and economic development, the situation of ecological security was still unstable.

China's 60 years of industrial transformation reviewed

In China, the real industrialization and modernization process started in 1949, when the Chinese people were emancipated from the yoke of the Kuomintang and the People's Republic of China (P.R.C) was founded. However, the road of emancipation has been a bumpy one. In particular, the emancipation of the mind has often been full of twists and turns. The tremendous liberation of social productive forces originated in the emancipation of the mind, whose truth has been tested by economic development practices. In the past 60 years China has paid tremendous efforts and costs in pursuit of emancipation, and today it still needs to emancipate the mind anew. For 60 years, since the formation of P.R. C, the country has kept pursuing the emancipation of the mind while exploring ways of change in institution, strategy and policy. In the first 30 years China attempted to devise an idealistic approach of transition to the socialist planned economic system, which was characterized by continuous revolution and movement. In the second 30 years China explored a realistic approach of transition to the socialist market economic system, which is characterized by incremental reform and opening-up. For six decades industry has remained at the forefront of transformation. The emancipation of the mind and the realization of change aim to ultimately make China a strong nation with an affluent people. The purpose of the six-decade struggle in new China is to erase the stigma of "being poor and blank," secure a firm and strong foothold in the world, restore China's status as a world power and let the Chinese people enjoy the affluence and welfare of a well-off society. The central mission of this national revitalization is to realize industrialization. Therefore, industrialization has been the central theme of China's revitalization in the past 60 years. After 60 years of industrialization, hundreds of millions of Chinese people are now able to enjoy ever-increasing wealth from industrial civilization. However, still a larger proportion of China's 1.3 billion people are awaiting industrial civilization. In this sense, industrialization is not only the focus of China's socioeconomic development but also the world's largest livelihood mission. Industrial development is more of a means of enhancing people's livelihood than a means of regaining the title as a world power. This will become one of the distinctive characteristics of China's industrialization in the new stage.
