本文以云南省50个植物类群中的4个类群为研究对象，探讨了云南省农业生物多样性的保护与促进策略。这些植物是食用魔芋（Amorphophallus）、药用巴黎、毛果麝香草（Musella lasiocarpa）和野生茶（Camellia sinensis及其野生近缘种），包括它们的栽培品种和野生种群。通过对目标植物的分析，我们认为，保护和促进农业生物多样性应采取以下策略：（1）就地保护农业生物多样性，包括野生种群的生境保护、传统农业生态系统中乡土物种和品种的维护以及相关的环境教育;（2）迁地保护和促进农业生物多样性，包括建立活体标本库和种质库，以及将物种和品种引入农业生态系统用于农业实践;以及（3）通过可持续利用，包括繁殖、栽培、病虫害控制、农场和农场外管理的技术开发，以及新品种培育和科学研究等其他活动，促进和保护农业生物多样性。本文制定的策略将有助于在农业生态系统、物种、品种或地方品种以及管理系统层面保护和促进农业生物多样性。
This paper deals with strategies for agrobiodiversity conservation and promotion based on studies on four plant groups (selected from 50 plant groups) occurring in the Yunnan Province of China. These plants are edible konjac (Amorphophallus), medicinal Paris, Musella lasiocarpa and wild tea (Camellia sinensis and its wild relatives), including their cultivars and wild populations. After analyzing the target plants, we conclude that the following strategies should be adopted to conserve and promote agrobiodiversity: (1) in situ conservation of agrobiodiversity, including habitat protection of wild populations, maintenance of native species and varieties in traditional agroecosystems, and relevant environmental education; (2) ex situ conservation and promotion of agrobiodiversity, including establishment of living collections and germplasm banks, and introduction of species and varieties into agroecosystems for agricultural practice; and (3) promotion and conservation of agrobiodiversity through sustainable uses, including technique development of propagation, cultivation, pest and disease control, on farm and off farm management, and other activities such as new variety breeding and scientific studies. Strategies developed here will be helpful to conserve and promote agrobiodiversity at agroecosystem, species, variety or landrace, and management system levels.
