海南省生态盈亏及其空间结构研究

Ecological Profits and Losses and Their Geographical Distribution in Hainan Province

以生态足迹计算方法和泰尔指数等区域差距计算方法为模型工具,对海南的生态盈亏及其空间结构进行了系统研究。结果表明:海南省总量生态盈亏(ED)为2 357 083 hm2。在各项生态生产性土地中,盈亏较高的是总量水域、总量林地和总量耕地生态盈亏,较低的是总量草地、总量建设用地和总量化石能源用地生态盈亏。在18个市县中,总量耕地生态盈亏最高的市县是海口市,最低的是临高县。海南省人均生态盈亏为0.267 983 hm2。其中,人均水域、林地和耕地生态盈亏较高,人均草地、建设用地和化石能源用地生态盈亏较低。在18个市县中,人均生态盈亏最高的市县是文昌市,最低的是白沙县。

This paper researches the ecological profits and losses and their geographical distribution in Hainan Province using the calculus of ecological footprint and theil index.In conclusion,the total quantity of the ecological profits and losses in Hainan Province are 2 357 083 hm2.In the ecologically productive land,the ecological profits and losses of total water area,total forest land and total cultivated land are higher.The ecological profits and losses of total meadow land,total land used for building and total land used for landification are lower.In all 18 counties in Hainan Province,the maximum is in Haikou and the minimum is in Lingao.The quantity of the ecological profits and losses per capita in Hainan Province is 0.267 983 hm2.The ecological profits and losses of water area,forest land and cultivated land per capita are higher.The ecological profits and losses of meadow land,land used for building and land used for landification are lower.In all 18 counties in Hainan Province,the maximum is in Wenchang and the minimum is in Baisha.
