Spatial distribution of the sub-basins in the Yanhe basin

23
In terms of the strahler classification, the Yanhe River is divided into three stream levels,
24
with 3 being the highest level; thereby, the Yanhe basin is also divided into 35 sub-basins.
25
The letters from A to Q signify the trend from upstream to downstream. In comparison
26
table, for “2, 1-B”, “2” stands for the second sub-basin located in the northwestern part of
27
the Yanhe basin; “1-B” stands for the second (“B”) stream in the first (“1”) stream level.

Figure 7 The closeness relationship between land use and ecosystem services by
41
correspondence analysis (CA)
42
43
In the CA, two sets of points are marked as two types of symbols and represent land use
44
type in a given year and ecosystem services, separately. The distance between the points in
45
one set is a measure of similarity between them. The distances between the points in
11
46
different sets are measures of the tightness of linkage between them. Plot abbreviations:

63
In the CA, two sets of points are marked as two types of symbols and represent sub-basins
64
and ecosystem services, separately, in a given year. Plot abbreviations: WR, water retention;
65
WY, water yield; C_A, the average crop yield for farm land pixels in a sub-basin; C_S, the sum
66
of crop yield for farm land pixels in a sub-basin. The illustrations of the serial number for the
67
sub-basins in the plot are as follow: the letters from A to Q signify the trend from upstream
68
to downstream. For example, “1-B”, “1” represents that the stream within the sub-basin is
69
classified as the first (lowest) stream level, “B” represents that the stream within the sub-
70
basin is the second stream in the first stream level and is located in a relatively upstream
71
area
