摘要
Abstract
Based on the emergy theory,an estimate of cultivated land use intensity in Nanjing from 2000 to 2015 was made and its temporal variation was analyzed.Then the contribution rate of each influencing factor to cultivated land use intensity in Nanjing was analyzed by gray correlation method.The results showed that:The cultivated land use intensity in Nanjing was increasing;among the input factors,the intensity of agricultural machinery was increasing rapidly,and the labor force,agro-chemical fertilizer and pesticide concentration were declining.The coupling degree between cultivated land use intensity and construction land area was the strongest among the influencing factors.关键词
