Studies show that,during the analysed period,Chuzhou City's industrial structure has changed markedly,having undergone two transformations.The influence of industrial structure on natural environment from 1974 to 1995 increased as a whole,while from 1996 to 2004,the influence of industrial structure on natural en- vironment decreased year-on-year.These changes indicate that the regional change of industrial structure results in better ecological effects.Finally,we propose appropriate regulatory measures ac- cording to our research results.展开更多

文摘Nowadays the fast economic development has brought about serious conflicts between the limited land resources and the increasing land demand in Chuzhou City. The changes of land use structure also restrict economic development and society progress in this area. Because different cities have different functional localization, the city area and each county (city) have formed characteristic land utilization structure. It is of great significance to make rational use of land resources and ensure the sustainable use of land resources by analyzing the variation of land use structure in the city area and each county (city) in Chuzhou City. Based on the data of land use modification of Chuzhou City from 1996 to 2005 and adopting the quantitative analysis of landscape ecology, this paper studies quantitatively the temporal division of regional land use structure and its dynamic changes. The results indicate that: (1) this method can reveal the law of the variation; (2) the variation of land use structure in Chuzhou City: increasing diversification, evenness and heterogeneity; (3) the intensity of change in land use from 1996 to 2005 in the city appeared in the sequence: grass land > traffic land > garden land > virgin land > forest land > industrial and residential land > cultivated land > other agricultural land > water facility land; (4) there were remarkable differences between the city area and each county (city) in the relative change and the land use structure change from 1996 to 2005.
