Analysis of Transformation and Driving Forces of Agricultural Land in Zhengzhou Based on RS
摘要
Abstract
The use patterns of land resources had significant changes with the development of economy and the adjustment of industrial structure in Zhengzhou. Land use changes in the past 20 years was analyzed by using TM data of Zhengzhou in 1988 and 2009,focusing on the changes of agricultural land and the driving forces. The results showed that in the study period,the area of urban construction land and transportation land had a substantial increase,with the increase rates of 183. 40% and 123. 39%, while the agricultural land had a significant decrease with the decrease rate of 4. 11%, indicating that the urbanization of Zhengzhou was visible. The correlation coefficient of agricultural land utilization in every region was calculated by analyzing of agricultural land in different regions of Zhengzhou, and it was found that the area of agricultural land in Zhengzhou city had the highest decrement,up to 159. 01 km2. It was suggested that the social factors were the main driving force of agricultural land changes,including policy factors,demographic factors and economic factors.关键词
