The geographical coordinates are 118°33′E longitude and 36°04′N latitude. The modern climate is a warm temperate monsoon forest type, with annual mean temperature of 13℃ and annual mean precipitation of 767 mm . The aridity is 11-- 3.0. So this region is the transitional environment between semiarid and展开更多

The results show that, the major rocks of the reduction graphite zone are graphite-quartz anorthosite, gabbro. The major rocks of the oxidation graphite zone are marble with graphite, biotite granite, monzogranite. The main minerals of the reduction zone are plagioclase, pyroxene, quartz, pyrite. The graphite is aphanitic graphite appearing as dense massive, layered, spherical aggregates. The main minerals of the oxidation zone are calcite, quartz, K-feldspar, biotite, amphibole, chlorite. The graphite is flake graphite uniformly dispersed in the loose, and strongly erosion rocks. A large number of rocks in the area have been suffered chloritization, regional metamorphism, indicating that the formation of the graphite deposit should be related with gabbro melting. The carbon source in the lower part was taken into the mine, and then experienced regional metamorphism.展开更多

Studying the territorial inequality of the net income per peasant was an emphasis of this paper, and Shandong Province was pointed as the case study region. By the help of logistic regression, it could be found that the special distribution of the net income per peasant in Shandong Province was affected by three factors： distance to No.308 National Highway, distance to the coastline in the east of Shandong Province, and urbanization rates. Based on the decomposition of Gini index, the net income per peasant was divided into four parts, and it was found that the income from family business and salary were the two major sources of income. As to the mechanism for income inequality, it was proved that urbanization was still the key factor. In order to reduce income inequality, the local governments should promote urbanization through improving road networks, such as building highways, which could connect rural areas with the major nodes such as big cities and the port cities in the east.展开更多
