Conversion Margins for the Major Uses of Agricultural Land and Their Variations in Shandong Province, China

It is of practical significance for the decision-making on country food security and farmland protection to analyze the conversion margins for the major uses of agricultural land and their variations. Based on the panel data of wheat, corn, vegetable, fruit, and forests productions from 520 investigated farmer households of 13 investigated villages in Shandong Province from 2003 to 2009, and using Cobb-Douglas production function, the revenue conversion margins can be obtained separately, between different grain-crops (wheat, corn) and different non-grain crops (vegetable, fruit, forests), and the conversion relationship between growing grain( wheat, corn) and going out for non-farm work. The results show that from 2003 to 2009, growing wheat and corn are more economically and reasonably for farmers, compared with growing vegetable, but growing wheat and corn are becoming less economically and less reasonably day by day, compared with planting forests. Moreover, the conversion margin between wheat and fruit shows obvious scissors difference. Just from 2007, farmers’ growing fruit became economically and reasonably, but until 2009, compared with going out to work after abandoning farm8land, growing wheat had no economic rationality. From 2003 to 2009, farmers’ growing corn is more profitable than growing fruit and going out for non-farm work after abandoning farmland. The subsidies for wheat and corn have increased farmers’ comparative income from food production remarkably, but the subsidies cannot change the general tendency that farmers transform food (wheat, corn) production into non-food (especially forests) production. The revenue difference between growing wheat, corn and vegetable and growing fruit and forests is being pulled ceaselessly bigger, and the tendency that farmers transform wheat, corn and vegetable growing lands into fruit and forests growing lands has become increasingly apparent.

山东半岛南部近海表层沉积物中脂类生物标志物的组成及形态分析

分析了山东半岛南部近海表层沉积物中游离态和碱不稳定结合态脂类物质的组成,结果显示:脂肪酸呈现以16∶0为主峰的单峰形分布趋势,具明显偶碳优势,海源为其主要来源,脂肪酸主要以结合态形式存在,不同类别的脂肪酸形态分布略有差异,脂肪酸的结构和来源是影响脂肪酸形态分布的重要因素;同样以海源为主的甾醇则主要以游离态形式存在,但陆源甾醇的结合态比重相对较高;烷烃呈现以C29烷烃为主峰的单峰形分布趋势,陆源输入是其主要来源;烷烃主要以游离态形式存在,且UCM(不可分辨成分)峰仅出现在游离态烷烃的气相色谱图中。     

Research on the hierarchical structure of the metropolitan system and economic development of the provincial capital urban circle in Shandong

Regional development is the trend for future urbanization, and the urban circle is a highly efficient economic spatial pattern of regional development. This study selects statistical data of urban area population, GDP, and the output value of tertiary industry for seven cities in China – Jinan, Zibo, Tai’an, Laiwu, Dezhou, Liaocheng, and Binzhou – in the Shandong provincial capital urban circle from 2005 to 2009. It uses the principles and Zipf model, rank-size rule, and Lotka logarithmic model to analyze and study the hierarchical structure of the metropolitan system and economic development of the Shandong provincial capital urban circle. Based on the above research, this paper provides references for decision-making on enhancement of the metropolitan system structure, improvement in core city primacy index, the optimal adjustment of industrial structure and the optimal allocation of essential resources.     

临沂九曲沂河大桥附近沂河古河槽特征

选择临沂九曲沂河大桥附近沂河断面作为研究剖面.根据九曲沂河大桥的地质勘探钻孔资料,绘制了沂河古河槽地质剖面示意图.沿勘探钻孔进行了浅层地震影像法物探.在下游的G327沂河大桥附近河槽底部和上游约3 km枋河右岸的埋藏阶地上采集了年代样品,获得了1个光释光年代、2个14 C年代.结论认为:沂河古河槽底部断裂带、裂隙发育;九曲沂河大桥附近约53～55 m以下河槽为末次盛冰期时沂河、祊河的古河槽,当时枋河在九曲沂河大桥的下游汇入沂河;约54 m以上为晚冰期以来沂河河槽,晚冰期以后,枋河约在现在入沂河的位置注入沂河.由于河槽宽浅,流量季节变化大,形成分汉-辫状河特征.     

山东茶叶生产现状与开发对策

山东省“南茶北引”的成功，特别是近年来茶园的规模发展，使山东省成为江北茶区最北部的茶园集中分布区。茶叶生产取得了良好的经济效益，成为山东省广大低山丘陵区一个新的经济增长点。但是山东省的自然环境条件对茶树生长的诸多限制因素，阻碍了山东省茶树生产的发展。如何打破自然条件的限制，更好地发展茶叶生产，成为山东省实现经济、环境可持续发展的一个亟待解决的问题。在对山东省茶叶生产现状分析的基础上，提出了切实可行的发展对策。     

Economic Periodicity Analysis of Shandong Province

The paper analyses the periodical characteristics of the economic development of Shandong Province by using the minimum variation analysis model. The analysis shows that the economic development process of Shandong Province has short, medium and long cycles respectively for 6, 12, 19 years, and the fluctuation of the economic development becomes gentler with time passing by. The fluctuation of macro-control policy, investment and consumption are the main reasons of the economic fluctuation.
