浙江毛竹林生态经营技术的PRA-DPSIR评价

融合参与式农村评估(PRA)和"驱动力-压力-状态-影响-响应"模型(DPSIR)2种工具,对浙江11个主要毛竹县(市)1 591户竹农的经营技术开展分析评价。结果表明,浙江竹农毛竹经营采伐强度较大、土地负载高、粗放随意;对留笋养竹、立竹保留量、采伐时间和对象、垦复砍杂等通用技术以及作为新兴基础设施的水分管理有待改进,土壤生态化管理和施肥则需要优先考虑。应强化面向农户的应用技术推广,避免急功近利式的经营导向,重视土壤水肥管理基础上的综合措施应用,确保生态可持续前提下的经营产出。

PRA-DPSIR Assessment of Ecological Management Techniques for Moso Bamboo Forest in Zhejiang

The PRA and Driving force-pressure-state-impact-response (DPSIR) were integrated to conduct a survey assessment on Moso forest management techniques used by 1 591 households from 11 Moso bamboo (Phyllostachys pubescens)producing counties of Zhejiang. The results showed that the Moso forests were extensively managed at farmers' will featured with high intensity and high land production load. Both the routine techniques of bamboo shoot thinning, sanding culm quantity maintenance, felling time/object, stand site improvement, and the moisture management as the burgeoning infrastructure await improvement while soil ecological management should be focally prioritized. It was suggested that household-oriented application of Moso management techniques be strengthened to avoid the forest management eager for short-term benefts, and attention be paid to soil nutrient/water management integrated cultivation measures to ensure lasting production with ecological sustainability.
