喀斯特风水林和荒山生态系统碳储量的研究（英文）
|
摘要
所研究的风水林和荒山属于喀斯特地貌。喀斯特森林是一种脆弱的低生物量生态系统,土壤贫瘠,自我修复能力低,易受人为因素干扰。风水林指人们居住地附近的一片茂盛的森林,认为有神居住而崇拜,严禁被砍伐和破坏。荒山是喀斯特森林植被在人为干扰后出现岩石裸露产生的石漠化现象。该研究通过野外调查、实验室分析、数理统计等对广西罗城喀斯特风水林和荒山生态系统碳储量进行对比性研究。结果表明:喀斯特风水林植被、土壤和枯落物碳储量分别是荒山的7.42倍、5.9倍和1.1倍,风水林和荒山生态系统碳储量分别为137.06、93.73 t·hm~(-2),其中土壤碳库贡献率最高,而林下植被和枯落物却较低,表明风水林森林生态系统碳储量明显高于荒山。通过风水林和荒山的碳储量比较研究,为评价风水林碳汇提供依据,为制定森林管理政策、保护村社水平的植被提供数据参考。此外,还探讨了少数民族朴素的生态伦理思想在保护森林和增汇方面的作用,丰富了生态伦理学内容,对传承和弘扬少数民族传统文化、恢复生态具有重要意义。
Holly hill and barren hill both exist in karst landform,karst forest is a fragile and low-biomass ecosystem with barren soil and low resilience and resistance capabilities to disturbance. The holly hill is the place where the vegetation is well protected by the indigenous people who live nearby based on their beliefs,the barren hill is comprised of rocky karst formations that contain the areas of exposed bedrock due to human disturbance. The study is about comparison of carbon storage of ecosystem in holly hill and barren hill,the carbon stocks of holly hill and barren hill ecosystems were studied through field work,laboratory analysis and statistic at Luocheng,Guangxi,China. The results showed that vegetation,soil and litter carbon storage of holly hill ecosystems were 7.42,5.9 and 1.1 times those of barren hill ecosystems respectively. Carbon storage were 137.06,93.73 t·hm~(-2) at holly hill and barren hill ecosystems respectively,soil carbon storage contributed most in the two ecosystems,and understory and litter contributed less. The comparison of carbon storage of holly hill and barren hill reflects the importance of protecting karst forest,keeping traditional aboriginal culture means a lot for protecting ecological environment and improving carbon sequestration.
