of social fragmentation score with the flood
map (figure 2), thus revealing four types of
social fragmentation trend. Type one is char-
acterized by social fragmentation scores that
remain continually below the average for all
townships. Such types can be represented as
“continuous high social fragmentation,” which
includes Dongshi, Budai, Yizhu, Lucao, Puzi,
Liujiao and Xinkang. Type Two is characterized
by social fragmentation scores that change from
positive to negative, indicating increased social
fragmentation. Type Two is labeled “trans-
formed social fragmentation,” and includes
Shuishang and Zhongpu. Type Three exhibits
fluctuating social fragmentation, and includes
Dalin, Meishan, Zhuqi, Fanlu and Alishan, and
this type is termed “fluctuating social fragmen-
tation.” Finally, Taibao is categorized as Type
Four because of its higher social fragmentation
score than the average of all townships. Type
Four thus is named “continuous low social
fragmentation”.
