摘要:
为了研究广西喀斯特石漠化演变特征，选择2000，2004，2008，2012年MODIS NDVI数据，结合研究区的土地利用数据和土壤数据，采用基于归一化植被指数（NDVI）的像元二分模型估算了研究区的植被覆盖度，根据石漠化与植被覆盖度的对应关系，反演了研究区不同时相的石漠化信息，分析了石漠化总体演变特征、演变轨迹，并探讨了石漠化演变与环境背景因素、气候因素、社会经济因素、石漠化治理政策因素的关系。结果表明：1）2000—2012年研究区石漠化面积总体呈先迅速减少后又略有回升的趋势，石漠化改善与恶化并存，石漠化演变动态度最快的为轻度石漠化，动态度为3.73%；2）13 a间，石漠化演变轨迹为改善型的面积占喀斯特总面积的11.60%，反复型的占9.54%，恶化型的占3.69%，4个研究时段均为石漠化的面积仅占1.59%，改善面积大于恶化面积；3）石漠化演变过程受环境背景因素、气候因素、社会经济因素、石漠化治理政策因素的共同影响。
Abstract:
In order to understand the evolution characteristics of karst rocky desertification in Guangxi, MODIS NDVI data of 2000, 2004, 2008 and 2012 were selected to estimate vegetation coverage in the study area by combining the data of land use with soil data of study area and using the dimidiate pixel model based on NDVI; the rocky desertification information of different phase in the study area were derived, the evolution characteristics and track were analyzed according to the corresponding relationship between rocky desertification and vegetation coverage. Relationships between karst rocky desertification and environmental background, climate, social-economic and rocky desertification control policy factors were discussed, respectively. The result showed that: 1) the overall trend of rocky desertification was rapidly reducing first and then recovering slightly in the study area from 2000 to 2012, improvement was compatible with deterioration，mild rocky desertification had the fastest change rate, dynamic degree was 3.73%; 2) during the 13 years, the improved type accounted for 11.60% of the total karst area, repeated type accounted for 9.54%, deteriorated type accounted for 3.69%, rocky desertification area of not variant type occupied only 1.59%，improved area was greater than the degraded area; 3) karst rocky desertification evolution was mutually influenced by the factors such as environmental background, climate, social-economic and rocky desertification control policy.
