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.     

On the Population Structure of the Kamchatka Sable

The degree of morphological differentiation of sable (Martes zibellina L.) populations was studied in different physiographic regions of the Kamchatka Peninsula and the Penzhina River basin. According to craniometric data, the sables inhabiting the hilly Western Kamchatka Plain are larger than the animals from other regions. However, the analysis of phenetic variation in craniological characters and coat color showed that the sable samples taken within the peninsula were fairly homogeneous. On this basis, all sables inhabiting the Kamchatka Peninsula may be regarded as a single population.

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.     

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.     

Climate changes and overstory recruitment of larch at the northern timberline in the Yamal Peninsula

Studies on overstory recruitment of the Siberian larch (Larix sibirica Ledeb.) in open larch forests depending on the time of seedling establishment (1880–1980) have been performed in the northern timberline ecotone on the Yamal Peninsula. Two periods of active larch establishment have been revealed: from 1900 to 1935 and from 1950 to 1970. A comparison of these data with the results of instrumental observations on temperature and precipitation has shown that the overstory recruitment of larch in valleys of northern rivers is largely dependent on July air temperatures in the first years of tree life, when seedlings grow 10–20 cm high.
