【摘要】：利用遥感定量测量,采用Landsat-5的NDVI数据和TM数据及其他辅助数据,结合生态学方法,对长江三角洲地区的4个省市1995年和2005年的生态资产进行了测量,并对生态资产分布格局及其驱动因素进行了分析。结果表明:该地区的生态资产分布不均衡,表现为由南向北逐渐递减的趋势。1995—2005年,生态资产减少量达1 273.35亿元,减少率达23.37%。从生态资产构成来说,湿地和水体的生态资产减少的幅度最大,分别为58.42%和41.78%;耕地、灌丛和林地的减少量也在20%左右。长三角地区生态资产发生变化既是自然因素作用的结果,也是人为活动直接作用的结果。在这一地区城市化不断扩大的情况下,应大力提倡生态环境的保护,构建人与自然的和谐发展。
[Abstract]:The ecological assets of four provinces and cities in the Yangtze River Delta in 1995 and 2005 were measured by using remote sensing quantitative measurement, NDVI data of Landsat-5, TM data and other auxiliary data, combined with ecological method.The distribution pattern of ecological assets and its driving factors were analyzed.The results showed that the distribution of ecological assets in this area was not balanced, showing a decreasing trend from south to north. In 1995-2005, the amount of ecological assets decreased to 1 27.335 billion yuan, and the reduction rate was 23.3737 yuan.In terms of the composition of ecological assets, the ecological assets of wetlands and water bodies decreased by 58.42% and 41.78% respectively, and the decrease of cultivated land, scrub and woodland was about 20%.The change of ecological assets in Yangtze River Delta is not only the result of natural factors, but also the direct effect of human activities.Under the circumstances of the continuous expansion of urbanization in this area, the protection of ecological environment should be vigorously advocated, and the harmonious development of man and nature should be constructed.
