Abstract: |
The state-owned Qingxi Forest Farm in Dongguan city preserves a typical southern subtropical
evergreen broad-leaved forest, which is a natural reference system for restoring and reconstructing the ecosystem
of the southern subtropical evergreen broad-leaved forest, and has extremely important economic and ecological
value. After field investigation and survey, the value accounting index system of forest ecological products in
Qingxi Forest Farm was constructed, which was composed of four types of service functions: support, regulation, supply and culture, and was evaluated from 18 functions in 7 categories: soil conservation, forest nutrient sequestration, water conservation, carbon sequestration and oxygen release, air purification, biodiversity,
and forest health care. The assessment results show that the value of ecological products of forest ecosystem in Qingxi Forest Farm is 798 million yuan / year. Among them, carbon sequestration and oxygen release (399. 012
million yuan / year) > water conservation (227. 635 million yuan / year) > biodiversity (79. 595 million yuan /
year) > cultural services (57. 631 million yuan / year) > air purification (16. 116 million yuan / year) > soil conservation (13. 62 million yuan / year) > nutrient sequestration (4. 637 million yuan / year). On the whole, the total ecological value of Qingxi Forest Farm gradually increased and then decreased from south to north. |
