摘要:山东夏津黄河故道古桑树群是中国黄河流域农耕文明的杰出代表,评价与分析其生态系统服务功能,对全面认识古桑树群系统的生态特征与价值,明确其以防风固沙为核心的服务功能在维持古桑树群生态系统结构与功能稳定方面的重要作用,促进黄河故道地区农业环境与生态系统保护具有重要意义。夏津黄河故道沙化区根据当地沙地特征,因地制宜,形成了以桑树为主,林、果、农复合的稳定生态系统,有效促进了风沙土的土壤熟化进度,为生态系统恢复奠定了基础。本文基于数据可获取性及古桑树群主要生态功能,运用物质量评估方法,定量计算并分析了古桑树群生态产品供给、防止风蚀、固沙保水、土壤改良和大气调节5项生态系统服务功能。结果表明,夏津黄河故道古桑树群系统内400hm2古桑树每年可比无林地多涵养水1.2×105m3,减少泥沙流失1.8×104t;吸收CO219 716t、释放O2约为14 340t、吸收SO2137 600t,滞尘约21.54t,生态效益显著;此外,古桑树群系统还提供了以桑椹为代表的丰富的生态系统产品及林下间作的农产品;得益于古桑树群区域古树、沙丘、河流、村庄的协调发展,以古桑树群为核心的生态旅游也发展迅速。
Xiajin Yellow River Ancient Mulberry Trees Group is a prominent representative of farming civilization in the Yellow River.The evaluation and analysis is helpful to comprehensive understanding ecological characteristics of the system,clear the core role of windbreak and sand-fixation service function in maintaining stability of ecosystem structure and function,and promote agricultural environment and ecosystem protection.According to the characters of local sand,the people of Shandong Xiajin wind sandy wasteland of Yellow River Old Riverway adjust measures to local conditions,and form the stabilized ecological system which compound with the forest,fruit and agriculture.This ancient mulberry-based fruit tree community system effectively promotes the sand soil curing schedule,which laid a foundation for ecosystem recovery.This paper,based on the data availability and main ecological function of system,use material quality assessment method,calculate and analyze five ecological service functions,including supply of ecological products,prevent wind erosion,sand-fixing and water-preserving,soil improvement,and atmosphere adjustment.The research shows that the Xiajin Yellow River Ancient Mulberry Trees Group can conserve water 1.2×105 m3,and reduce sediment loss 1.8×104 t,absorb CO249.29 tand dust 10.11 tper hectare per year than non-forest land.In addition,Xiajin Yellow River Ancient Mulberry Trees Group also provides rich fruit products and understory interplanting crops.Benefit from the coordinated development of ancient trees,sand dunes,rivers,and the village of Ancient Mulberry Trees Group,the ecological tourism with ancient mulberry trees as core is developing rapidly.
