3.2 | Similarity of taxa
The TS between the KMF and the HMF
was 55.89% at the species level and 83.38% at the genus level.
Nitrariaceae
which was only distributed in 10 counties was not found in the Hengduan
Mountain, and the minimum TS was 96.88% at the family level. Therefore,
family level TS estimates had little value for further assessing
patterns in biodiversity. The TS of woody species and herbaceous species
were 57.52% and 55.67%, respectively. According to the endemic taxa
data, the TS of endemic species was 70%, and the endemic genera in the
Kunlun Mountains were also found in the Hengduan Mountains. The TS of
woody genera and herbaceous genera were 82.05% and 83.86%,
respectively, while the TS of genera with both woody and herbaceous
species was 72.73%.
In the 28 county-level geographical units, the TS
of the counties decreased from the
east to the west, and increased from the north to the south (Table 1).
At the species level, the maximum TS was 93.86% in Banma County and the
minimum was 24.53% in Wuqia County. The TS was higher than 50% in the
eastern section, it was 40%–50% in the middle section and was less
than 40% in the western section of the Kunlun Mountains
(Table 1). At the genus level, 26
counties had TS estimates higher than 80%, and
2 of the 26 counties had TS
estimates of 100%, named Banma County and Gande County. The minimum TS
was 76.61% in Ruoqiang County, while the TS of Wuqia County was 78.75%
(Table 1).
