Temporal Patterns of Shrub Vegetation and Variation with Precipitation in Gurbantunggut Desert, Central Asia

Table 1

The design of temporal patterns (5 time durations × 6 time lags) of precipitation for analyzing the relationship between current NDVI and different combinations of duration and lag precipitation. The numbers in the cells indicated the time interval for which precipitation was accumulated (0 indicated the current 16-day period, 1 indicated the first previous period, 2 indicated the second previous period, 0-1 indicated precipitation was accumulated from current period to the first previous period, 0–2 indicated precipitation was accumulated from current period to the second previous period, etc.).

Lag	Duration
	1	2	3	4	5
0	0	0-1	0–2	0–3	0–4
1	1	1-2	1–3	1–4	1–5
2	2	2-3	2–4	2–5	2–6
3	3	3-4	3–5	3–6	3–7
4	4	4-5	4–6	4–7	4–8
5	5	5-6	5–7	5–8	5–9
