SPSS13.0 was used to process the data of the 1-6 batch of key cultural relic conservation units promulgated by the State Administration of Cultural Heritage of China;and multi-element evaluation method was used to calculate the composite distribution index.The spatial distribution of cultural relics of provinces in China can be divided into four grades,namely:very rich areas,rich areas,poor areas and very poor areas;the article analyzes the characteristics of cultural resources in spatial and temporal distribution.The paper holds that(1)the distribution of China's cultural relic tourism resources is relatively concentrated,different sharply from region to region,with more Han nation's heritage,less relics of the ethnic minorities;(2) Henan,Hebei,Shaanxi,Shanxi Province are the main regions with heavy distribution of cultural resources;(3) relics appeared in specific time periods in China's history.Ming and Qing Dynasties,Sui,Tang and Five Dynasties,Song,Liao and Jin,the Western Han,Shang and Zhou dynasties,the New Stone Age are the major periods producing more cultural relics.This paper also analyzes relationships of the emergence of cultural relics with production technology,specific historical process,specific geographical location,political system,religion,national culture,customs,architectural styles and techniques of the traditional cultural educational system.Finally,the paper discusses the development and protection of heritage.
Combining the integrated technology of ecological quantity analytical method with GIS technology, based on the Landsat TM images and SPOT images in 1995 and 2009, this paper made a quantitative analysis of the changing process of land use/cover. The results showed that land use/cover in study area had undergone obviously changes from 1995 to 2009. The artificial landscapes which were mainly tropical crops plantation increased dramatically, natural forest and rubber forest was substantially reduced. The major patterns of land use change in the study area were the conversions of the natural forest and rubber forest to tropical crops plantation and cultivated land, cultivated land converted to tropical crops plantation and residential area. The analysis of landscape index showed that the role of landscape structure more diverse and uniform with the diversity of landscape fragmentation increases, the dominance of natural forest and rubber forest on the overall control of landscape reduced under the influence of human activities in the study area. The driving force analysis showed that economic development, agriculture industrial structure, policy and technology factors were the dominant factors of land use/change in the study area in the short term.
