corresponding to the different scales (Table 5), we fo<strong>und</strong> that the total spatial<br />
variation of soil moisture was mostly dominated by variations of soil variables<br />
within a short-range scale in UG 99, CG and HG, but a long-range scale in UG<br />
79 and WG. SWC had a positive correlation with organic carbon, whereas a<br />
negative correlation with either sand content or bulk density, which was<br />
consistent with single scale analysis. Noted that sand content was the main soil<br />
variable controlling SWC, as shown by the high correlation coefficient at different<br />
spatial scales.<br />
