摘要
桑树具有十分强大的土壤保护功能。本文基于全国生态功能区划,瞄准生态桑在土壤保持生态系统服务功能中持续作用的重大科学问题,考量了桑树在各类生态重点区域的定位和价值实现途径。通过分析各生态区域蚕桑产业发展的基础状况,确定了西南喀斯特区、川滇干热河谷区、三峡库区、黄土高原区、鲁中山区和昆仑山区等6个桑树土壤保持核心服务区。针对上述6个桑树土壤保持核心服务区的产业生态特征,分别提出了保墒增碳、护土保水、保土降污、屯水治沙、肥土增碳和防风固沙的土壤管理技术,并推荐了广西宜州、四川盐边、重庆巫溪、陕西榆林、山东烟台和新疆和田等6个技术先行示范区。
Mulberry trees have a very powerful soil conservation function.This article was based on the national ecological function zoning,targeting the major scientific issue of the sustainable role of ecological mulberry in soil conservation ecosystem services,and considering the positioning and value realization pathways of mulberry trees in various ecological important areas.By analyzing the basic situation of sericulture industry development in various ecological regions,six core service areas for mulberry soil conservation were identified,including the Southwest Karst Region,the Sichuan Yunnan Dry and Hot Valley Region,the Three Gorges Reservoir Area,the Loess Plateau Region,the Luzhong Mountain Area,and the Kunlun Mountain Area.Furthermore,based on the industrial ecological characteristics of the six core service areas for soil conservation of mulberry trees,soil management technologies for soil moisture and carbon enhancement,soil and water conservation,soil and pollution reduction,water and sand control,soil carbon enhancement,and wind and sand fixation were proposed.Six technology leading demonstration areas were recommended,including Yizhou in Guangxi,Yanbian in Sichuan,Wuxi in Chongqing,Yulin in Shaanxi,Yantai in Shandong,and Hotan in Xinjiang.
