Analysis of Ecosystem Disturbance in Economic Corridor Along Southern Silk Road Based on Land Use

doi:10.3969/j.issn.1674-0696.2018.06.11

Abstract

Abstract: The spatial and temporal variations of ecosystem disturbance resulting from land use in the economic corridor along the Southern Silk Road using the ecosystem disturbance index based on land use data obtained from the Climate Change Initiative (CCI) project of the European Space Agency (ESA) were analysed.Results showed that ecosystem disturbance indexes in most of Malaysia，northern Indochina，and the northwest part of South Asia were relativly high，while the ecosystem disturbance indexes in most of South Asia，southern Indochina，and northeastern Malaysia were relatively low in 1992 and 2015.The ecosystem disturbance index in the economic corridor along the Southern Silk Road showed an increasing trend from 1992 to 2015.The ecosystem disturbance index in southwestern China，Brunei，the Philippines and Timor-Leste showed a decreasing trend.The decreasing of the natural regeneration type and increasing of the artificial regeneration type are main causes that result in the increasing of the ecosystem disturbance index in the economic corridor along the Southern Silk Road.

Key words: environment engineering, land use, ecosystem disturbance, spatial pattern, Southern Silk Road

摘要： 基于欧洲宇航局气候变化启动计划的土地利用数据，利用生态系统干扰指数分析土地利用对“南方丝绸之路”经济带生态系统扰动时空变化的影响。结果表明：1992年和2015年“南方丝绸之路”经济带生态系统扰动指数呈现马来群岛大部、中南半岛北部、南亚西北部较低，南亚大部、中南半岛南部和马来群岛东北部较高的特点；24 a间生态系统扰动指数整体呈增加趋势，仅有中国西南地区、菲律宾、文莱和东帝汶等国家生态系统扰动指数呈下降趋势；自然再生利用型生态系统减少以及人为再生利用型生态系统增加是造成“南方丝绸之路”经济带生态系统扰动指数增加的主要原因。
