Abstract:

Rurality is an important index to describe and identify the characteristics of rural. That means the rural has the characteristics of rural. It can indicate the differences between city and rural. The connotation of rurality is being to express from the perspective of land use. Land resources are the carriers of rural characteristics, which can be used to evaluate rural change by the way of land use. Rural has its special functions, such as rural production, rural life and rural ecology. So land use can be used to reflect changes in rural. The evaluation system of ruralilty in town based on land use had been established. The 11 indexes had been selected from 3 aspects. The farmland proportion, the change rate of cultivated land, the rate of cultivated land and household settlements, the change rate of forest were reflected rural production. The rural construction status, the scale of household settlements, the concentration degree of household settlements,the rate of length of household settlements joining with farmland were reflected rural life. The rate of water, wetland,forest were reflected rural ecology. The weight of the indexes were calculated by using Delphi and AHP methods. Main results for this study were as follows: 1) The index and intensity of rurality in 2000 and 2010 of Panyu District and Conghua District had been calculated. The results showed, the rurality indexes were decreasing in 10 years in the two districts.The average value of rurality indexes in Panyu and Conghua were 0.355 and 0.684 in 2000, and the average value were 0.260 and 0.540 respectively in 2010. That revealed the rurality indexes of Panyu District were obviously lower than Conghua District, and the differences of rurality indexes in Panyu's town were decreasing gradually, while the differences in Conghua's town were increasing. 2) The rurality indexes of Panyu and Conghua were divided into five grades: stronger, strong, medium, weak and weaker. In 2000, the weak level of rurality was the main type in Panyu District, but in 2010, the main type was the weaker. In Conghua District, the grade of rurality areas in Conghua District decreased significantly, only the stronger and strong levels appeared in 2000, 10 years later, the strong grade disappeared, and the weak grade appeared. 3) There had a significant correlation between the rurality index and some factors, such as elevation, the farming total output value, the proportion of the two and three industry, the road areas, the level of urbanization and so on. Panyu District belongs to the metropolitan area of Guangzhou, but Conghua District belongs to the ecological protection area, so the rurality is more significant in Conghua that in Panyu, the results matched the fact. It proved that the evaluation system of rurality based on land use could reflect the characteristics of rural in a right way, and it is a practical research method for rurality.

Key words: rurality, rurality index, land use, town scale, Guangzhou City
