摘要
南京江北新区是2015年经国务院批准设立的国家级经济开发区。以研究南京江北新区土地利用格局变化为目标,结合1985、1995、2004、2014年4期遥感影像资料和相关文献资料,运用ENVI非监督分类解译手段和地理信息系统统计分析方法,全面分析江北新区土地利用及土地利用转移数据。系统总结了江北新区近30年土地利用变化的时空规律,对影响江北新区土地利用变化因子进行了初步探析。研究结果表明:1985—2014年,江北新区土地利用主要变化是建设用地迅速扩张和耕地面积大幅度下降(二者增减面积几乎相等),建设用地与耕地是被转化最为明显的用地类型。林地及未利用地面积小幅度增加,水域、草地面积小幅度减少。不同的时间段,土地利用变化也表现出不同的规律(1985—1995年,以草地增加为主要特征;1995—2004年,耕地面积与草地面积大幅度减少的同时,建设用地较大幅度增长;2004—2014年,林地增加但其余用地类型变化相应减缓)。南京江北新区土地利用变化的主要影响因子可以归结为工业化与城市化发展,产业结构调整和政策调控。
The Nanjing Jiangbei New Area （JBNA） is the state-level economic development zone whose establishment was approved by the State Council in 2015.In this paper,we aimed at exploring the land use changes in JBNA by using remote sensing data in 1985,1995,2004 and 2014,the methods of unsupervised classification to interpret image by using ENVI software and the statistical analysis methods in Geographic Information System （GIS）,in order to acquire land use patterns and land use transitions.We analyzed and summarized the utilization of spatio-temporal change in land use in JBNA in the last 30 years for the first time and combined the literature and social economic data to preliminarily analyze the driving factors.The result indicated that：the rapid expansion of urban area accompanied with a big decline in the cropland dominated in the whole study district while the increase is almost the same to the decrease.The two are the obviously translated main land uses as well.In addition,there was a slight increase in forest and unused land area while a slight decreasing in the water body and grassland from 1985 to 2014.In different phases,it showed different pattern in land use changes：from 1985 to 1995,the increase of grassland was the major characteristic.The cropland and grasssland decimated while the urban area increased greatly during the period of 1995 to 2004.From 2004 to 2014,forest area grew while the others changed slowlier.The main influencing factors for land use change in JBNA could be attributed to the determinants of industrialization and urbanization development,industrial restructuring and policy of regulation control .
