Coniferous forest ecosystem services value in Jiangxi Province of China: A dynamic analysis
摘要
Abstract
According to the Specifications for Assessment of Forest Ecosystem Services in China (LY/T 1721-2008) , an analysis was made on the coniferous forest ecosystem services value in Jiangxi Province in the ninth (1996-2000) and the tenth (2001-2005) five-year periods. From the ninth to the tenth five-year period, the total value of the coniferous forest ecosystem services in the Province had a slow increase, from 367 billion yuan per year to 377 billion yuan per year and with an annual increment of 2. 92% , but the service value per year per hectare decreased from 70. 4 thousand yuan to 69. 3 thousand yuan, with a decrement of 1.55% . The permutation orders of the coniferous forest ecosystem' s six services values during the two five-year periods were the same, and the first two (the values of water conservation and of carbon fixation and oxygen release) occupied 81.6% of the total. Among the services values, water conservation value was the largest, making important sense to the Jiangxi Province with severe soil and water loss, whereas the carbon fixation and oxygen release values as well as their proportions in total value had the most rapid increase. In the coniferous forests in Jiangxi, young and middle-aged forests were the main parts, with a great potential of carbon sequestration.关键词
