In this paper, an empirical research on the relationship between urbanization of Henan Province and income of farmers is conducted by introducing VAR model and applying the data of urbanization and farmers' income in Henan province from 1978 to 2014.The results show that the higher the urbanization level, the greater the farmers' income, quantitatively, 1 percent increase in urbanization rate can lead to 2.87 percent increase in rural per capita net income.Therefore, Henan should follow the path to urbanization and continue to improve the urbanization level, perfect social security system and land management system, strive to develop tertiary industry and agriculture with distinctive features, and increase farmers' income through urbanization.
Tazhong Oil Field CIII1 Reservoir is a fault block reservoir with condensate gas cap in the upper part and side bottom water in the lower part. This paper studies the development characteristic of 3 stages of single well production test and producing, decreasing pressure with high production and overall water injection development, and analyzes the factors which affect the development effect. It shows that the formation pressure change of this reservoir depends on the production rate, the production gas oil ratio is obviously affected by formation pressure, and the formation energy consumption decreases the formation flow pressure. It proposes a formation pressure limit value for the preservation and restoration of formation pressure and reasonable water injection rate, production rate and development. This study has referential significance for the development of oil and gas reservoirs of the same type.
Abstract The Xujiaweizi fault depression is rich in natural gas resources in Lower Cretaceous and a major fault depression of the deep strata in northern Songliao Basin. In this study, the tight gas is coaliferous gas in the K 1 sh Formation of the Xujiaweizi Fault Depression. The methane carbon isotope value of tight gas is controlled by mature evolution. The cause of reversed sequence and partially reversed sequence of gas components carbon isotope is carbon isotope fractionation with hydrocarbon generation evolution of high-overmature stage source rock. The carbon isotope values of the low content components are obviously lighter with the increase of buried depth at the late stage of mature evolution. The carbon isotope values of adsorbed gas show similar characteristics, whether mudstone, carbargilite or coal in the same well. The tight gas reservoir is self-generation and self-accumulation gas reservoir by vertical diffusion and short distance migration in the K1sh Formation of the Xujiaweizi Fault Depression. It is important to study on the geochemical characteristics and the genesis of tight gas for guiding the exploration and deployment in the future.
Twelfth Five-Year Plan is to strengthen three ruralissues which are rural area,farmer,agriculture,to build a harmonious rural areas,but the key issue is strengthening the village-level financial management,eliminating financial vulnerability to create a harmonious atmosphere for the new rural construction.
The study area of this paper is Dingxi County, a typical loess gully\|hilly region of the semi\|arid regions. The land use maps in 1990 and 2000 were compiled from the Landsat TM images and other data resources. There are 9 kinds of land use types. The slope data derived of contour lines. Referring to some metrics of the landscape ecology, 10 metrics were selected or developed for quantifying the land use characteristic, monitoring the land use changes and analyzing the relationships between land use, land use changes and the topographical condition, governmental policies of the Dingxi County. Some conclusions were obtained. The selected metrics can quantify the land use and land use change in typical loess gully\|hilly region, Dingxi County. The land use and land use change have good spatial distribution regularities in the slope grades. The governmental policies are the primary driving factors for the land use changes in our study area. The policies are reclaiming the slope farmlands and grassland into terraces, rainfall\|collection works, and reforesting and regressing some sloping cultivated lands.
By factor analysis,this paper selects 30 indexes,by which it evaluates and classified the difference of economic development level in the regions of Heilongjiang Province. The results show that the differences are obvious. The principal component which causes these differences can be summarized as comprehensive economic strength,industry development,land use,population and infrastructure development; the cumulative contribution rate can reach 96.028%. Based on cluster analysis,the whole province can be divided into four kinds of economic areas. They are the area with higher level of economic development,the area with better level,the area with underdeveloped level and the relatively poor area. The classification better with the fact of regional economic differences of Heilongjiang Province.
Presents regional mapping model, a new model of feedforward neural network for pattern recognition which realizes a mapping from the input parameters′ region to output region for every class and its features that the criterions of training and classification are the same, and the classification is more reasonable and natural, and the change of the error function can increase the training speed.
Natural Gas are attracted by new energy. NGH act new method for natural gas transportation and storage,it have advantage than LNG,such as trustiness?safety?low fee and so on. The paper introduced condition of formation and vantage of hydrate transportation with NGH.
