Abstract: The automatic and accurate estimation method for gross primary productivity of a forest ecosystem based on a remote sensing technology includes: the real-time position signals of a remote sensing collection device is acquired, the forest map is acquired and the real-time position signals is displayed on the map; the meteorological parameters and forest characteristic parameters of the forest are collected by a remote sensing collection device, and the preliminary estimation on the GPP of the forest ecosystem is performed by a ground estimation model; the geomorphological features of the map are collected, it is judged whether to correct the preliminary estimation result according to the geomorphological features, and if the correction is needed, the preliminary estimation result is adjusted; and the adjusted estimation result is stored, and the dynamic fluctuation chart of the adjusted estimation result is displayed on a visual device.

Abstract: A cigar cabinet includes a refrigerating assembly and a humidifying assembly. The humidifying assembly includes a water collecting trough, a drain trough and a guide trough. The guide trough is located under the refrigerating assembly. The drain trough and the water collecting trough are arranged on a bottom wall of the cigar cabinet with a partition arranged therebetween. The height of the partition is less than that of the side wall of the water collecting trough, or the partition defines a passage connecting the drain trough and the water collecting trough, and the bottom height of the passage is less than the side wall height of the water collecting trough. The drain trough defines a drain hole for discharging liquid to thereby prevent condensed water overflowing from the water collecting trough, and the water collecting though without drain hole can store water to keep the humidity inside the cigar cabinet.
