| 摘 要： | [目的]对河南省近10a来植被覆盖度及其景观格局的时空变化及其驱动因素进行分析,为区域经济—社会—环境持续协调发展提供决策参考。[方法]基于2000,2003,2006,2009年MOD13Q1数据集,借助ArcGIS 9.3和Fragstats 3.3软件平台进行定量分析。[结果]10a尺度上,河南省植被覆盖以高覆盖度为主,总体覆盖度呈现先下降后上升的特点,2003年最低,为72.64%;2009年最高,为76.48%;极高植被覆盖度区域主要分布在豫西的林区,最低区域主要分布在城市建成区、大型水库和沿黄河生态涵养带;城市与建成区植被覆盖度呈现波动中下降趋势且其植被覆盖度等级景观格局向恶性方向发展,农田区和自然植被区则与城市建成区变化趋势相反。[结论]降水和气温的变化、快速城镇化以及河南省城镇化、新型工业化、新型农业现代化协调发展战略的实施是导致上述河南省植被覆盖度及其景观格局变化的主要原因。

| Abstract: | [Objective] The objective of the paper is to study the spatial-temporal changes and driving factors of fractional vegetation coverage(FVC) and its landscape pattern in He'nan Province in the past decade in order to provide a support for the regional sustainable development of society, economy and environment.[Methods] Based on dataset of MOD13 Q1 in 2000, 2003, 2006 and 2009, we did the quantitative analysis under ArcGIS 9.3 and Fragstas 3.3.[Results] At a time scale of 10 years, the regional FVC was dominated by high FVC grade. The overall FVC decreased firstly and then increased. The lowest FVC was 72.64% in 2003, and the highest was 76.48% in 2009. The areas with extreme high FVC distributed in forested areas of western He'nan Province. And the areas with the lowest FVC distributed in urban and built area, large reservoirs and the ecological conservation zone of Yellow River. The FVC declined in urban and built area, but increased in cropland and natural vegetation areas. The landscape pattern of cropland and natural vegetation areas was improved, but urban and built area was on the contrary. The areas with an obviously decreased FVC mainly distributed in urban and built area.[Conclusion] The main reasons for the change of fractional vegetation coverage and its landscape pattern in He'nan Province were the local changes in precipitation and temperature, rapid urbanization and the implementation of coordinated development strategy of urbanization, new-type industrialization and agricultural modernization. |
