摘要:

基于地学信息图谱分析方法,运用ARC/INFO软件,以马尔柯夫空间概率模型为基础,利用新开河流域33 年(1969-2001 年) 土地利用格局4 期的空间数据(1969 年、1979 年、1992年、2001 年),合成了一系列土地利用格局变化图谱,通过图谱分析来了解新开河流域的土地利用格局变化规律。结果表明:在过去33 年期间该流域土地利用格局发生了显著变化。耕地大幅度增加,其净增面积1357.2 km2,占流域总面积超过32%,其主要来源于草地、沙地、沼泽地、林地;沙地变化有所起伏,占流域总面积不低于23%,虽然总体呈减少趋势,但流域的草地沙化、耕地沙化还比较严重;草地大幅度减少,其净减面积1582.6 km2,占流域总面积由36.2%缩减为18.5%,其主要来源于开垦草地为耕地、草地退化成沙地、沼泽地、盐碱地以及草地改造种植林地;居民地、盐碱地呈增加趋势,湿地、林地呈减少趋势。

Abstract:

In this paper, the research is conducted based on the geographic information TUPU analytic methods and Markov model of space probability. With the support of ARC/INFO software, this paper has compounded a series of varying TUPU of the land-use pattern by using spatial data covering four periods (1969, 1979, 1992 and 2001) in the Xinkai River basin. We can comprehend the changes of land-use pattern in the Xinkai River basin through the TUPU. The result shows that great changes have taken place on the land-use pattern in this basin during the past 33 years. The farmland has a net increase of 1357.2 km2 (exceeding 32% of the total basin), and most of it was converted from grassland, sandy soil, marsh and woodland. The changes of sandy soil somewhat oscillated. The area of sandy soil accounted for less than 23% of the total basin area. Although the sandy soil tended to decrease on the whole, the desertification of grassland and farmland is still serious in this basin. The grassland has decreased greatly. It has a net reduction of 1582.6 km2 from 36.2% to 18.5% of the total basin area. The main reasons are summarized in three respects: first, grassland has been cultivated into farmland; second, grassland has degenerated into sandy soil, marsh and saline land; third, grassland has been transformed into plantable woodland. The residential land and saline land show a decreasing trend while the wetland and woodland present an increasing trend.
