中文摘要	【目的】植被恢复是石漠化治理的核心,研究典型喀斯特石漠化地区植被变化趋势及其与气温、降水的关系,为明确后期植被恢复的重点区域和可利用的关键气候因子提供决策依据。【方法】基于20002014年MODIS-NDVI数据集资料,结合相同时期观测的气温与降水数据,运用均值法、趋势线分析法和相关分析法来分析贵州省安顺市NDVI的变化趋势及其对降水和气温的响应特征。【结果】20002014年,石漠化严重地区安顺市植被覆盖呈明显的上升趋势;植被覆盖增加的区域主要集中在海拔相对较高且石漠化严重的紫云县和镇宁县,而植被覆盖减少的区域主要分布于北部安顺市西秀区普定县平坝县交界沿线以及主要县级行政中心所在地及其周边地区;年均降水量与年均气温对安顺市NDVI的变化影响不大,而在月际NDVI变化尺度上,气温条件则是植被生长的关键因素;NDVI变化对气温和降水均没有明显的滞后效应或滞后时间较短。【结论】在后期安顺市生态修复及石漠化综合治理过程中,应加强对北部植被覆盖减少区域的治理;充分利用气温因子的作用,合理安排植被培育、栽植等管理活动;同时应以创建国家森林城市为契机,不断提高植被覆盖水平。
英文摘要	[Purposes]Vegetation restoration is the core of rocky desertification management.It aims to provide decision-making basis for clarifying the key areas of vegetation restoration and the available key climate factors in later stage,by studying the change tendency of vegetation and its relationship with temperature and precipitation in the typical Karst rocky desertification area.[Methods] Based on MODIS-NDVI data from 2000 to 2014,and precipitation and temperature data at the same period,it used the mathematics- statics methods,such as the average method,the trend line analysis and correlation analysis to analyze the change tendency of NDVI and its response to precipitation and average temperature.[Findings]The results showed that:vegetation coverage in Anshun City,where rocky desertification was serious,presented an obviously rising trend in the past 15 years.The areas with increased vegetation coverage mainly concentrated in the relatively high elevation of rocky desertification Ziyun County and Zhenning County. While the areas with reduced vegetation coverage mainly distributed along the Xixiu District-Puding-Pingba,as well as the main county administrative center and its surrounding areas.The average annual precipitation and average temperature have little impact on the change of NDVI in Anshun City.On the change scale of monthly variation of NDVI,the temperature condition becomes the key factor of vegetation growth.There is no obvious hysteresis effect or short lag time of NDVI change on temperature and precipitation. [Conclusions]In the process of ecological restoration and comprehensive treatment of rocky desertification in the later stage of Anshun,it is necessary to strengthen the management of the area with reduced vegetation coverage in the north and make full use of the effect of temperature factor to rationally arrange management activities,such as cultivation and planting.Meanwhile,Anshun City should take advantage of the creation ofNational Forest Cityas an opportunity to continuously improve the level of vegetation coverage.
