摘要

在对"两湖一库"(红枫湖、百花湖和阿哈水库)地区1973

1993

2001和2010年的4期卫星遥感影像进行解译的基础上

利用RS和GIS技术

建立区域土地利用/覆被类型空间数据库

定量分析了研究区域近40 a来土地利用/覆被时空变化特征及其生态环境效应。结果表明:(1) 该地区土地利用/覆被类型以旱地、水田和林地为主。(2) 与1973年相比

2010年荒草地急剧减少

只占区域面积的1.02%;建设用面积急剧增加

比1973年增加了207.93%;林地面积增加了13.51%;耕地面积(旱地、水田)减少了18.41%;水域面积增加42.06%。(3) 耕地主要向林地和建设用地转移

荒草地主要向林地和水域转移

林地则主要向建设用地转移。

Abstract

Based on the interpretation of satellite images of the "two lakes and one reservoir" in 1973

1993

2001 and 2010

using RS and GIS

the spatial database of regional land use/cover changes(LUCC) was established

and the LUCC characteristics of temporal and spatial variation over past 40 years was quantitatively analyzed; Meanwhile

the LUCC's impact on ecological environment was discussed. The results show that:(1) Dry land

paddy field and woodland are main land use/cover types in "two lakes and one reservoir"(Hongfeng Lake

Baihua Lake and Aha Reseruior) region;(2) Compared with 1973

grassland decreased rapidly

only accounting for 1.02% of the area; construction area increased 207.93%; the forest land area increased by 13.51%; area of cultivated land(dry land

paddy field ) decreased by 18.41%; the water area increased by 42.06%;(3) Cultivated land mainly transferred to the woodland and construction land

grassland transfered mainly to forest and water area

forest land mainly transfered to the construction land.
