Brigalow Catchment Study data.

The Brigalow Catchment Study (BCS) in the brigalow (Acacia harpophylla) bioregion of central Queensland, commenced in 1965 with a pre-clearing calibration phase of 17 years to define the hydrology of 3 adjoining catchments (12–17 ha). Following clearing of 2 catchments in 1982, 3 land uses, brigalow forest, cropping, and grazed pasture, were established and monitored for water balance, resource condition and productivity. This trial has provided data and scientific understanding on the interaction of climate, soils, water, land use and management for resource condition across the three major land uses. Soil samples from the trial site have been used in calibration of the Roth C model for use in estimating Australia’s national greenhouse gas inventory.

昆士兰州中部的brigalow（Acacia harpophylla）生物区开展的Brigalow流域研究（BCS）始于1965年，其前期为17年的清伐前校准阶段，旨在明确3个相邻流域（面积12–17公顷）的水文特征。1982年对其中2个流域进行清伐后，设立了brigalow森林、农作物种植和放牧草场三种土地利用类型，并对其水量平衡、资源状况及生产力进行监测。该试验为理解气候、土壤、水、土地利用与管理措施之间的相互作用，以及这些因素对三种主要土地利用类型下资源状况的影响，提供了数据支撑和科学依据。试验场地采集的土壤样本已用于Roth C模型的校准，该模型可用于估算澳大利亚国家温室气体清单。
