摘要

载畜量是正确评价牧场饲草潜力的重要指标之一。然而,在森林管理计划中,由于成本降低,无法增加这一领域的专业技术人员,因此,为牧场规划提出了简化数据收集的不同方法。本文提出了一种评估牧业价值的简化方法(最常用的承载力评估方法之一),并在实际条件下进行了评估,以获得整个牧场的适当潜在放养率。该方法基于之前的一项研究,该研究提出了一种简化的数据收集方法,该方法通过物种或植物科的不同功能组进行:适口草、不适口草,豆类,属于其他植物科的物种,多刺和有毒物种,树木和灌木。每个类别都通过一个总结饲料潜力的指数与其饲养行为联系起来,这允许将资源分类为不同的质量类别,每个类别都以给定的潜在放养率为特征。拟议的方法似乎也很容易由牧场管理中没有特定组成的工作人员执行,并且与传统程序进行比较产生了准确的结果。即使拟议的方案不应被视为原始方法的替代方案,但获取牧场资源管理信息也是有用的,尤其是在地区一级。

Proposal of a simplified method for pastoral value assessment inside forest planning
Carrying capacity is one of the most important variables that should be assessed for a proper evaluation of forage potentiality of pastures. Nevertheless, inside forest management plans, reduced costs make impossible the involvement of additional technical staff specialized in this domain and for this reason different methodologies to simplify data collection were proposed for pasture planning. In this paper a simplified method to evaluate the pastoral value (one of the most common procedure for carrying capacity estimation) is proposed and assessed in real conditions in order to obtain a proper potential stocking rate of a whole pasture area. The method is based on a previous research that proposed a simplified method of data collection that is performed by means of different functional groups of species or botanical families: palatable grasses, not palatable grasses, legumes, species belonging to other botanical families, spiny and poisonous species, trees and shrubs. Each category is linked to its feeding behavior by an index that summarizes forage potentiality and this permits to classify the resources in different quality classes, each of them characterized by a given potential stocking rate. The proposed methodology seems easy to be performed also by staff without a specific formation in pasture management and comparison performed with the traditional procedure produced accurate results. Even if the proposed scheme should not to be considered alternative to the original methodology, it can be useful to acquire information for pastoral resource management, especially at territorial level.
