By analogy, the next order watersheds were derived and named in order
third order watershed (Zone 3), fourth order watershed (Zone 4) and fi fth
order watershed (Zone 5), etc. Figure 5 illustrates the process of delin-
eating multi-scale watersheds for Site 1. Table 3 also lists the number of
scales for every monitoring site.

The number of scales and towns be covered for 27 monitoring sites.

1.2.4 AGRICULTURAL LAND USE INTENSITY FOR
WATERSHED
With more attention being paid to land use and land cover change, an ap-
proach to assess agricultural land use intensity including agricultural input
and output intensity on a general basis has been developed in our previ-
ous work [24]. The measurement and assessment of agricultural land use
intensity was preformed at municipal/town level because the agricultural
inputs and outputs information derived from census data are aggregated
and offi cially reported at this level, and this level also is the smallest
