摘要
黄土高原的环境压力是人类生存的压力, 小流域人居生态单元和生态基质是承载和反映黄土高原人居建设发展和水土流失变化双重压力的载体。压力的疏解是人居建设寻找符合多样的承载空间生态基质秩序的有机疏散或集中的建设模式。并由此提出山地末梢型的生态环抱先决、山地川道型的人居生态串珠和台塬型人居岛状自然环绕三种脆弱自然条件下疏解环境压力的城镇化发展模式。
The environmental pressure on the loess plateau is a pressure on human existence. Small watershed settlement units and their ecological matrix are the containers and media which reflect the double pressure of building of settlements and elusion of water arid in the loess plateau region. Mitigating solutions of such stresses could be explained by the evacuation of various models in respect of an organic dispersion or concentration of settlement building in accordance with the order of spatial ecological matrix.The article then proposes three urbanization models including ＂the ecological predetermined surrounding model in context of Mountain Twig＂, ＂thesettlement-ecology stringed beads model in context of CorridorValley ＂ and ＂ the natural surrounding model in context offlatlands ＂.
