ABSTRACT:
Quantifying landscape pattern and its change is essential for the monitoring and assessment of ecological consequences of land use
change and human interference. The changing characteristics of landscape structure in the Haihe River Basin (HRB), China, during
1990 to 2000 were detected by using satellite remote sensing based land use data. Key landscape indices were selected to
characterize the landscape patterns. The results showed that from 1990 to 2000, the landscape within the study area has undertaken a
complicated transformation in landscape structure and composition. A notable decrease in cropland mainly due to conversion to
built-up land. Spatial distribution of different patches became more separated and the patch types became more disaggregated.
Additionally, we found that both Shannon’s diversity index and Shannon’s evenness index increased during the periods, manifesting
the landscapes in the study area became more fragmented and heterogeneous under intensive exploitation and reconstruction of
landscape by human beings. The environmental effects of landscape change were also discussed.
1. INTRODUCTION
Landscape structure and composition develops continuously in
space and time. These developments are attributable to the
complex interaction between natural environment and human
activities, resulting in the change of the stability of individual
elements in the landscape system and the spatial structure of
landscape (Xiao et al., 1990). Investigating landscape structure
and its change is a prerequisite to the study of ecosystem
functions and processes, sustainable resources management, and
effective land use planning (Matsushita, et al., 2006). The
research on regional landscape change has been one of the hot
topics in this field, which attracts general interests of the
geographers and ecologists worldwide (Forman and Godron,
1986; Dong, et al., 2007). Landscape and environmental
changes are interrelated and interact on each other. Studying on
landscape change and associated environment takes quantitative
analysis of landscape change as preexisting. The methods of
quantitative analysis of landscape pattern structure and its
change based on landscape metrics have been widely adopted
by landscape ecology researchers (Herold, et al., 2003; Olsen,
2007).
Haihe River Basin (HRB), which suffered intense human
interference and decreasingly deteriorating environment, has
been an important commodity grain base and ecology
conservation base in north China and holds an increasingly
important social and economic position. A severe lack of water
resources, integrated with tremendous landscape change
jeopardized the ecosystem stabilization, structure and function.
Accordingly, the study on landscape changes in this area can
improve our understanding of the interrelationships among
landscape structure, natural environment, and human activities,
and help to define the magnitude and direction of landscape
changes caused by human interfering activities, and thus
provide an important scientific basis for the sustainable
development of the region (Lu, et al., 2003). The main issue is
the interpretation of the magnitude and pattern of change and its
effects on the regional ecological processes and patterns. There
have been some academic researches on landscape change in
provinces Beijing, Tianjin, and Hebei according to
administrative boundary, almost all of which focused on the
urbanization process (e.g. Xiao, et al., 2006), but few reports on
landscape change analysis at the basin scale based on remote
sensing (RS) and geographical information system (GIS).
Therefore, our objectives of the present study are: (1) to
characterize the land use change in the Haihe River Basin,
China; (2) to quantify the changes in landscape pattern in HRB;
and (3) to evaluate the effects of landscape pattern changes on
environment.
2. MATERIALS AND METHODS
2.1 Study Area
Haihe River Basin is located between 35°~43°N and
112°~120°E. It neighbors the Inner Mongolia Plateau in the
north, and Yellow River is the borderline in the south. It faces
the Bohai Sea to the east and borders Shanxi Plateau in the west
(Figure 1). It has a typical warm to temperate, semi-humid and
semiarid, continental monsoon climate, and well-defined
seasons. The Haihe River Basin, with an area of 318,000 square
kilometers, involves primarily Hebei Province and two huge
municipalities, Beijing and Tianjin. Other four Provinces, such
as Inner Mongol, Shanxi, Henan, and Shandong, partially fall
into the Basin. Haihe River Basin is one of the most developed
regions in China. About 10 percent of the China’s population,
15 percent of nation’s industrial and 10 percent of the total
