从广佛都市圈1990、1995、2000、2005和2010年5期土地利用矢量数据中提取出耕地、林地、园地和水域4类农林业用地.基于Costanza等生态系统服务价值计算方法,在对谢高地等提出的“中国陆地生态系统单位面积生态服务价值”进行区域修正及功能性和经济性调整的基础上,估算了1990—2010年间广佛都市圈农林生态系统的生态服务价值.结果表明:1990—2010年间,随着经济的不断发展以及人们生活水平的不断提高,居民对农林生态系统服务的支付意愿和支付能力逐年增强,使得广佛都市圈农林生态系统服务价值总体上呈波动上升趋势,1990、1995、2000、2005和2010年的服务价值分别为413.74×108、612.83×10~8、582.88×10~8、773.44×10~8和698.67×10~8元,20年间提高了284.93×10~8元,平均年增幅为2.7%.研究期间,总服务价值增加最多的为水域,达166.74×10~8元,其次为林地和园地,分别增加了103.01×10~8和47.74×10~8元.耕地的服务价值则降低了32.56×10~8元,降幅达23.1%.在空间分布上,广佛都市圈各年的农林生态系统服务价值均表现为从东北和西南部向中部减少的趋势.各类型农林生态系统服务价值所占比例在年际间变化不大,总体表现为:涵养水源>废物处理>生物多样性保护>气候调节>土壤形成与保护>气体调节>娱乐休闲与文化>原材料提供>食物生产.
Extracted from the Guangzhou-Foshan metropolitan 1990,1995,2000,2005 and 2010 land use vector data 5 out of arable land, forest, garden and water four categories agroforestry land. Costanza service value calculation method based on ecological systems, in Xie Heights and so on. Based on the regional revising and functional and economic adjustment of the ecological service value per unit area of terrestrial ecosystem in China, the ecological service value of agroforestry ecosystem in Guangfo metropolitan area was estimated from 1990 to 2010. Results It shows that in 1990-2010, with the continuous development of economy and continuous improvement of people’s living standard, residents’ willingness to pay and ability to pay for agroforestry services have been increasing year by year, making the value of agroforestry services fluctuated in Guangfu metropolitan area as a whole upward trend, 1990,1995,2000,2005 and services value in 2010 were 413.74 × 108,612.83 × 10 ~ 8,582.88 × 10 ~ 8,773.44 × 10 ~ 8 and 698.67 × 10 ~ 8 yuan, 20 years to improve Up by 284.93 × 10 ~ 8 Yuan with an average annual increase of 2.7% .While the total service value increased most during the study period, it was 166.74 × 10 ~ 8 Yuan, followed by forest land and garden land, increasing by 103.01 × 10 ~ 8 and 47.74 × 10 ~ 8 yuan service value of farmland is reduced 32.56 × 10 ~ 8 yuan, a decline of 23.1% in the spatial distribution, service value for each year of forest and agricultural ecosystems Foshan metropolitan area showed from the northeast and southwest Ministry of Agriculture, Forestry and Fisheries of China, Ministry of Agriculture of China, Ministry of Agriculture of China, Ministry of Land and Resources, Beijing 100083, China) The proportion of service value of various types of agroforestry systems varies little by region from year to year. The overall performance is as follows: Conservation water> Waste treatment> Biodiversity conservation> Climate regulation> Soil formation and protection> > Recreation & Culture> Raw Materials> Food Production.
