摘要
将规范分析与实证分析相结合 ,提出了一个评估区域各点位土地利用 土地覆盖变化的新方法 :(1)采用相对原则观察一时段内的变化方向 ;(2 )物理模型与统计模型相结合 ,基于区域实际情况建立生境适宜性参照基准 ;(3)用多变量分析方法量度各点位与参照基准的差异。结合GIS和遥感技术 。
Most of sustainable studies have adopted a normative approach. They attempt to employ common value judgements in assessing human-natural relations and in designing future plans. In practice, however, great regional differentiation precludes the fair use of common principles. This paper, while borrowing some ideas from normative studies, presents a positivist based approach to regional sustainable development assessment: (1) the achievement of sustainability in a region should be judged by the changing direction in a time period concerned; (2) the principle of judgement is whether the changes suit the local environment; (3) in terms of land use and land cover (LULC), a hybrid model that integrates ideas from both the physically and the statistically-based model types, was proposed to develop typical suitable site conditions as benchmarks in determining the suitability of a specific land use type; (4) a multivariate technique was used for measuring the difference between benchmarks and the actual situation. By using this approach, as well as GIS and remote sensing techniques, LULC changes in the Middle Yiluo Basin of the Yellow River were investigated in a fine geographical scale.
