项目摘要

This study analysed the landscape structure of the regional system, which mediates livelihood at the household level and economic factors at the national level, avoiding the problem, often found in the study and governance of rural Africa, of the scale gap among observations at different scales, and of the mismatch between the scales of observation on the one hand, and explanation and management on the other. It applied local lacunarity analysis to high-resolution satellite images of Mount Meru, and illuminated 1) the landscape structure by up-scaling landscape information derived at the micro scale, 2) characteristics of landscape elements through the analysis of scaling information, and 3) geometrical properties of the extracted landscape elements. The landscape structure at the meso and regional scale is expected to serve as fundamental information that is useful for wider and regional investigation of micro household processes including land inheritance and subdivision.

这项研究分析了区域系统的景观结构，区域系统在家庭一级协调生计，在国家一级协调经济因素，避免了在非洲农村研究和治理中经常发现的问题，即不同尺度的观察之间的尺度差距，以及观察尺度与解释和管理尺度之间的不匹配问题。对梅鲁山高分辨率卫星影像进行局部空隙分析，从微观尺度上提取景观信息，揭示景观结构，通过尺度信息分析景观要素的特征，提取景观要素的几何特征。预计中尺度和区域尺度的景观结构将作为基本信息，有助于更广泛和区域地调查微型家庭过程，包括土地继承和细分。
