文摘The research reviewed the concept of family farm and analyzed family farm types including unified, facility rental-oriented, employment-oriented, circular and grain＆oil based family farms, as well as corresponding demands in technology and policies. Based on the analysis, the research proposed countermeasures and suggestions. It is necessary to define the range and scale on family farm before giving policy supports. It is important to establish access system of industry and commerce capital to rural areas to guarantee the operators in need be benefited from national preferential policies. Meanwhile, new system on land transfer should be established to guarantee security system for family farm, improve socialized service system and promote government-built production facilities operated by farmers.
文摘[Objective] The paper aimed to reflect the spatial pattern and temporal and spatial evolution characteristics, the differences between inter-regional tourism economy was measured from the quality aspect, which provided a reference for the local governments in the future tourism development. [Method] Using the location entropy methods, three time periods side of tourism-related date of 2000, 2005, 2007 were selected, from the angle of the spatial pattern and the evolution of the differences within the different scales, the spatial and temporal evolution characteristics of the economic development level of Jiangsu were analysed. [Result] The results showed that from the aspect of spatial evolution pattern, as time goes on, the economic development of Jiangsu tourism has experienced morphological evolution of concentration- dispersion decrease-stability; when it comes to the development of the tourism economy, in recent years, the overall gap between the tourism economy in Jiangsu did not widen, the gap mainly led by the region one after another. According to their volatility, it will be divided into four categories: A Stable type (Wuxi, Xuzhou, Lianyungang and Taizhou), B Increasing type (Huai’an), C Fluctuations type (Nanjing, Changzhou, Suzhou and Yangzhou) and D Depression type (Nantong, Yancheng, Zhenjiang and Suqian). [Conclusion] Location entropy was quoted into tourism economic analysis, the method was simple and easy to understand, the result was accurate and convincing, which provided a reference for travel economic development and investment decision-making of Jiangsu.
文摘By taking 65 counties and cities of Jiangsu Province as empirical units, rurality indexes have been constructed based on regional urban-rural integration, and a quantitative evaluation has been conducted on the rurality of Jiangsu Province based on county scale. With the support of ArcGIS 9.3, GeoDA 095 and SPSS 16, by adopting Jenks best breakpoint classification and spatial autocorrelation analysis, quantitative analysis and research have been conducted on the spatial differentiation of rurality of Jiangsu Province. The results show that the rural difference of Jiangsu Province based on county scale is not remarkable, and the area with strong rurality takes a larger proportion; rurality increases from South Jiangsu to North Jiangsu progressively; rurality concentrates in general, seven counties and cities including Jiangyin and Kunshan City are "cold points" while seven counties and cities including Guanyun and Funing City are "hot points" of rurality.
