Based on the field investigation data and related literatures, this paper analyzed the ecological issues in the breeding and utilization of highly cold-resistant and high-yielding rubber germplasm in Xishuangbanna, and the loss risk of this germplasm. The rubber farmers in Xishuangbanna had built a cycle pattern of establishing rubber nursery and managing rubber plantations to develop the local rubber industry, but the unlimited utilization of this germplasm made the rubber plantations expand to the highland with an elevation of 1300 m, resulting in the ecological issues such as the destruction of natural forests and species, decline of soil fertility, regional drought, rubber diseases and insect pests, and human-elephant conflicts. This germplsm and its intellectual property were under transnational loss without any control, making even more potential ecological and economic risks. Great attentions should be paid by the related organizations to take effective measures to conserve this germplsm resource to reduce its potential risks.
基于实地调查数据和相关文献,本文分析了西双版纳高抗寒高产橡胶种质资源在培育与利用过程中出现的生态问题以及该种质资源的流失风险。西双版纳的胶农构建了建立橡胶苗圃和管理橡胶种植园的循环模式以发展当地橡胶产业,但这种种质资源的无节制利用使得橡胶种植园扩展到海拔1300米的高地,导致了天然森林和物种遭到破坏、土壤肥力下降、区域干旱、橡胶病虫害以及人象冲突等生态问题。这种种质资源及其知识产权正在跨国流失且无人管控,带来了更多潜在的生态和经济风险。相关组织应予以高度重视,采取有效措施保护这种种质资源,以降低其潜在风险。
