退耕区域林草资源有效利用的思考--以安塞县为例

Strategies about the Efficient Utilization of the Forest and Grassland Resources in De-Farming Regions——A Case of Ansai County

选择典型代表县域陕西省安塞县,以农户调查问卷数据和相关研究成果为基础,分析了林草资源有效利用的路径。结果表明:安塞县自退耕还林工程实施17年来,环境改善,资源量增加,生态效益明显,但其潜在的生态功能并未完全转化为经济功能。从自然资源角度和社会经济角度分析,林草资源有效利用的路径为:在维持良性生态环境的前提下,通过"舍饲+轮牧"方式,发展畜牧业;同时,将林草生态系统的碳汇功能显化,纳入碳汇市场进行交易。基于此,建议围绕林草—畜牧业链网结构和碳汇产业,优化以林草资源为中心的土地利用结构,实现安塞县生态经济系统的良性发展。

We analyzed the paths of efficient utilization of forest and grass resources based on the questionnaire data and the associated results of previous researches in Ansai County,Shaanxi Province,which is a typical region of Grain for Green Project.The results indicated that the environment condition of Ansai County has improved since the Grain for Green Project had been implemented for 17 years in this county.Meanwhile,the amounts of resources have increased and the ecological benefits in this area are significant.However,the potential ecological functions have not been fully transformed into economic functions.From the perspectives of natural resources and socio-economy,the paths of efficient use of forest and grassland resources are:developing the animal husbandry by the approach of‘barn feeding + rotation grazing'under the premise of maintaining a benign ecological environment;at the same time,manifesting carbon sink function of the forest grass ecosystem and bringing it into the carbon sink market for transactions.Based on this,in order to realize the benign development of eco-economic system in Ansai County,we suggest that the structure of land use as the center of the forest and grass resources around the chain-network structure of grass-animal husbandry and the carbon sink industry should be optimized.
