Land use capability systems do not present any considerations regarding recharge zones (RZs). To improve conservation planning, the objective of this study was to present a parametrization method for the land use capability of recharge zones (LUC-RZ). RZs were characterized as the upper thirds of the elevations of all slopes with rectilinear, concave and/or convex features in the terrains. The LUC-RZ were parameterized based on the slope of the middle third of the elevations. The proposed methodology was applied to the Doce River basin (DRB) in Brazil, and 27.9% of the total area was characterized as RZs. It was found that 61.9% of the RZs area could be exploited through agricultural and livestock use; however, the usability of most of these areas was conditional on the adoption of rigorous soil and water conservation techniques. The remaining 38.1%, which was equivalent to 10.6% of the DRB, was restricted to native forest cover. Of the 61.9% of RZs area that could be used for agriculture and livestock, 18.2% was occupied by native vegetation. These areas are protected by law and are responsible for several ecosystem services and thus must be preserved. The parameterization of the LUC-RZ was sensitive to pedogeomorphological characteristics. The methodology used for the determination of the recharge zones has a strong theoretical basis and was simple to implement and therefore has great potential for use in multicriteria analyses for determining recharge zones.

补给区土地利用能力

土地利用能力系统不考虑补给区 (RZ)。为了改进保护规划，本研究的目的是提出一种补给区土地利用能力（LUC-RZ）的参数化方法。RZ 的特征是所有斜坡高程的上三分之一，在地形中具有直线、凹面和/或凸面特征。LUC-RZ 基于海拔中间三分之一的坡度进行参数化。所提出的方法应用于巴西的 Doce 河流域 (DRB)，总面积的 27.9% 被定性为 RZ。结果表明，61.9% 的 RZ 区域可以通过农业和畜牧业利用；然而，大多数这些区域的可用性取决于采用严格的水土保持技术。剩下的38个。1%，相当于 DRB 的 10.6%，仅限于原生森林覆盖。在可用于农业和畜牧业的 61.9% 的 RZ 区域中，18.2% 被原生植被占据。这些地区受法律保护，负责多种生态系统服务，因此必须予以保护。LUC-RZ 的参数化对土壤地貌特征敏感。用于确定补给区的方法具有很强的理论基础并且易于实施，因此在确定补给区的多标准分析中具有很大的潜力。这些地区受法律保护，负责多种生态系统服务，因此必须予以保护。LUC-RZ 的参数化对土壤地貌特征敏感。用于确定补给区的方法具有很强的理论基础并且易于实施，因此在确定补给区的多标准分析中具有很大的潜力。这些地区受法律保护，负责多种生态系统服务，因此必须予以保护。LUC-RZ 的参数化对土壤地貌特征敏感。用于确定补给区的方法具有很强的理论基础并且易于实施，因此在确定补给区的多标准分析中具有很大的潜力。
