摘　　要：[目的]研究黑龙江沿边县市植被动态变化及其对经济因子的响应。[方法]利用1998～2007年黑龙江沿边地区SPOT Vegetation每旬合成的归一化植被指数(NDVI)数据集,研究了近10年黑龙江沿边县市植被动态变化特征,并分析了植被变化对经济因子的响应。[结果]1998～2007年黑龙江沿边地区总体植被覆盖率高,且植被变化基本向好的趋势发展;除呼玛县部分区域植被呈退化状态外,近10年黑龙江沿边地区植被整体状况处于基本保持与改善状态,植被状况基本保持不变和有轻微改善的地区分别占71.00%和26.81%。同时,1998～2007年植被指数与国内生产总值均有不同程度的增长,但两者间增长趋势并不完全一致;MNDVI与职工平均工资呈显著正相关(P<0.01),而与耕地面积呈显著负相关(P<0.01),且这种负相关关系具有延迟性,即第一年的耕地面积减少将对第二年、第三年的MNDVI产生持续的影响。[结论]该研究为黑龙江界河流域经济发展、生态环境保护等政策制定提供了科学依据。[Objective] The aim was to study the vegetation dynamic variation in the border area of Heilongjiang Province.[Method] Based on SPOT Vegetation NDVI data in each 10-day from 1998 to 2007,the vegetation dynamic variation in the border area of Heilongjiang Province in recent 10 years were studied,and the responses of vegetation variation to economic factors were analyzed in the paper.[Result] On the whole,vegetation coverage was high in the border area of Heilongjiang Province from 1998 to 2007,and showed increase rend.Except for some areas of Huma County,the whole vegetation condition in the border area of Heilongjiang Province was basically constant or improved,and the region with constant vegetation condition accounted for 71.00%,while the region with slightly improved vegetation coverage occupied 26.81%.Meanwhile,vegetation index and GDP showed increase trend on the whole from 1998 to 2007,but there was no complete consistency in their trends.In addition,MNDVI had significant positive correlation with average salary of local workers（P〈0.01）,while significant negative correlation with farmland area（P〈0.01）,and the negative correlation was delayed,namely the decrease of farmland area in the first year would affect MNDVI in the second and third year.[Conclusion] The study could provide scientific references for the establishment of policies about economic development and ecological protection in Heilongjiang River basin.
