摘要
利用1990年、2000年、2010年和2015年四期长江经济带土地利用数据,采用土地利用转移概率矩阵、标准差椭圆和谢高地等修正Costanza方法,深入分析了长江经济带的土地利用分布格局和转移方向,定量计算了整体生态系统服务价值,并对其空间分布格局进行研究,深刻地揭示了长江经济带土地利用变化及生态系统服务价值的基本特征和演变规律。结果表明:1)长江经济带土地利用类型以林地、耕地为主,但耕地面积持续减少,建设用地和水域持续扩张,林地主要转化为耕地和建设用地,且建设用地为主要转出方向,新增建设用地呈现"西南-东北"方向分布格局,重心在安徽安庆市、六安市和湖北麻城市交界地区移动。2)1990年、2000年、2010年、2015年长江经济带生态系统服务价值总量分别为37723.69亿元、37681.00亿元、37717.06亿元、37613.06亿元,呈现先减后增再减反复波动的态势,最终减少110.63亿元,其中林地对生态系统服务价值的贡献率最大,主导着区域内整体的变化趋势。3)长江经济带生态系统服务价值空间分布出现明显的不均衡性,洞庭湖、鄱阳湖、太湖及附近区域要远远高于其他地区,在成渝城市群、武汉城市圈、安徽北部以及江苏大部分地区呈现明显低于其他区域的低值区。
Based on the land use data of the Economic Belt of the Changjiang River in 1990,2000,2010 and 2015,the transition probability matrix of land utilization,the standard deviation ellipsoid and the XIE Gao-di modified Costanza methods are used to estimate the land utilization distribution pattern and the transfer direction of the Economic Belt of the Changjiang River,the value of overall ecosystem service was calculated quantitatively,and the spatial distribution pattern was studied. The basic characteristics and the evolution law of land utilization and ecosystem service value in the Economic Belt are revealed profoundly. The results show that：（ 1） the land utilization types in the Economic Belt are mainly the forestland and the arable land,but the arable land continues to decrease,the construction land and the water area continue to expand,the forest land is mainly converted tothe arable land and the construction land,and the construction land is the main direction of transfer,the new construction land presents ＂southwest-northeast＂direction distribution pattern,its the center of gravity moves within the boundaries of two provinces,namely Anqing City and Liuan City in Anhui Province,Lu’an City and Macheng City in Hubei Province;（ 2） The total value of ecosystem services in the Economic Belt in 1990,2000,2010 and 2015 were 3772. 369 billion yuan,3768. 1 billion yuan,3771. 706 billion yuan and 3761. 306 billion yuan respectively,showing a decreasing trend and then increasing trend and decreasing trend again. The situation eventually dropped by 11.063 billion yuan,of which the woodland contributed the most to the ecosystem service value,and dominated the overall trend of change in the region;（ 3） The spatial distribution of ecosystem service value in the Economic Belt shows obvious imbalance. The areas of Dongting Lake,Poyang Lake,Taihu Lake and nearby areas are much higher than those in other areas. In Chengdu-Chongqing urban agglomeration,Wuhan urban agglomeration,northern Anhui and most areas of
