资源简介:
The depth of snow was measured at 88 points on the saddle grid. The
500 x 350 m study area (17.5 ha) consisted of a grid of 8 rows of
stakes in an east/west direction and 11 rows of stakes in a
north/south direction (for a total of 88 stakes). The stakes were
located 50 m apart. Each stake was given a point identification
number starting with 1 in the southwest corner and progressing in an
easterly direction for each of the east/west rows so that if head of
this file represented the north compass point and the tail
represented the south compass point, then the grid would look like
this: 71 72 73 74 75 76 77 78 79 80 801(=80A) 61 62 63 64 65 66 67 68 69 70 701(=70A) 51 52 53 54 55 56 57 58 59 60 601(=60A) 41 42 43 44 45 46 47 48 49 50 501(=50A) 31 32 33 34 35 36 37 38 39 40 401(=40A) 21 22 23 24 25 26 27 28 29 30 301(=30A) 11 12 13 14 15 16 17 18 19 20 201(=20A) 1 2 3 4 5 6 7 8 9 10 101(=10A) Note that stakes along the east boundary of the grid, i.e. those
ending with the "A", were given new designations to
facilitate incorporation of the data into the Saddle GIS. Snow
depths at each of the stakes were recorded on a weekly to biweekly
basis throughout the period during which snow accumulation existed
on the Saddle.
研究人员在鞍部网格的88个测点上开展了积雪深度测量。该研究区域为500×350米(合17.5公顷)的网格,沿东西向布设8排测杆、南北向布设11排测杆,总计88根测杆,测杆间距为50米。所有测杆以西南角的1号测点为起点,沿东西向行依次递增编号。若将该编号表的顶部视为北方位、底部视为南方位,则网格编号布局如下:
71、72、73、74、75、76、77、78、79、80、80A(原标注为801)
61、62、63、64、65、66、67、68、69、70、70A(原标注为701)
51、52、53、54、55、56、57、58、59、60、60A(原标注为601)
41、42、43、44、45、46、47、48、49、50、50A(原标注为501)
31、32、33、34、35、36、37、38、39、40、40A(原标注为401)
21、22、23、24、25、26、27、28、29、30、30A(原标注为301)
11、12、13、14、15、16、17、18、19、20、20A(原标注为201)
1、2、3、4、5、6、7、8、9、10、10A(原标注为101)
需注意,位于网格东边界的测杆(即编号末尾带“A”的测点)被赋予了新的标识,以方便将数据导入鞍部地理信息系统(Saddle GIS)。在鞍部区域有积雪覆盖的整个周期内,研究人员以每周至每两周一次的频率,记录了每根测杆处的积雪深度。
