摘要:

本文在对海南岛1986年、1996年、2000年3个时期陆地卫星TM影像判读分析的基础上,建立了1∶10万比例尺土地利用数据库。并以此为基础数据,采用转移矩阵、地理网格、数学模型和影像判读等方法,对海南岛的土地利用动态变化进行了定性、定位、定量研究。研究成果有利于人们全面理解海南岛土地利用变化原因、过程和驱动力,并为土地利用规划、生态省建设提供科学依据。

Abstract:

Based on time series mapping of land use in Hainan Island, the dynamic changes of the land use in the island have been monitored using remote sensing and GIS. The methods used in this paper include: land use transition matrixes, land use dynamic mapping, mathematical models and image interpretation. All these methods are used separately to explore the characters and laws of land use changes in Hainan from different aspects. In fact, transition matrixes are good for describing the general trends of land use changes and conversion amount among different land use types. Land use dynamic mapping is often used to discover the changes of land use in time and space. Mathematical models are utilized to calculate the extent and speed of change, including increase and decrease of land area for different purposes. The method of image interpretation is easy to monitor the land use changes,such as mangroves,shelter-belt and sandy land in the coastal zone directly and visually. Therefore, the results of the study in Hainan show that integration of multiple techniques and multiple methods could help people gain a deep understanding about land use dynamics and the driving forces of these changes.

Key words: Hainan Island, land use, dynamic changes, research methods
