Shuitu Baochi Xuebao, 2000 黄土丘陵沟壑区农耕地类型具有裙带关系，从沟坝地、梯田和坡耕地的演化与发展来看，具有从高位到低位的时空演化过程，其效益具有简单到复杂，由单项到综合的迁变过程。通过对其效应的比较分析，明确了黄土丘陵沟壑区农耕地的潜势所在，并为黄土高原水土保持与农业的持续高效发展，提供了可行的科学依据。

A RESEARCH ON MOUNTAIN-SMALL-TOWN PLANNING STRATEGY BASED ON THE SUB-WATERSHED UNITS: A CASE STUDY OF GANDE TOWN OF ANXI COUNTY IN FUJIAN [PDF]
, 2017 流域作为一种重要的自然地理单元,在人类社会发展中发挥了特殊的作用.与大、中型城市相比,山地小城镇受自然条件约束较大,受其他社会经济因素影响的复杂程度较低,其规划建设应充分结合自然流域因素.而在快速的规划建设中,这一点往往被忽视.本文以福建省安溪县感德镇为例,采用流域生态评价方法,分析小流域生态建设与山地小城镇空间规划的关系,提出以小流域生态价值为导向的空间规划策略,并引导小城镇土地利用和各项建设.As an important physical geography unit, watershed ...
