The Elaborate Simulation And Application Study On The Climatic Resource In The Area Of The West Of LiaoNing

By using 30 years' cliamatic data of 16 stations of observatory and lOOmxlOOm DEM data in the area of the west of LiaoNing province, the assay analyzes the status quo and change trendency of climatic resource in the area of the west of LiaoNing province. In virtue of the technique of GIS, it also completes the elaborate simulation on primary climatic factors and applies to the work of climatic area partition about chaoyang jujube. The primary contents as follows:(1) Making use of 30 years' climatic data of the stations of observatory in the area of the west of LiaoNing province, it calculates and analyzes the status quo of climatic resource such as light, heat, water and so on. Then, utilizing the method of climatic trendency rate, it analyzes the change trendency of climatic resource during the recent 30 years in the area of the west of LiaoNing province.(2) In terms of the method of Mann-Kendall, the assay measures the mutation phenomenon of primary agricultural climatic resource in the area of the west of LiaoNing province. Results show that the change of agricultural climatic resource such as energy of light and quatity of heat exists distinct mutation phenomenon, but the time of mutation disaccords.(3) Based on 30 years' climatic data and complementary data of meteorologic sentry post in the area of the west of LiaoNing province, and on the method of multianalysis of regression and trend surface plan, the assay sets up a small gridding calculation model on the primary climatic resource in the area of the west of LiaoNing province. In addition, in the flat of ArcGIS, the assay adopts the method of mixed inserted value and then achieves the elaborate simulation product that possesses the space precision of 100m×100m.(4) Applying the elaborate simulation product of climatic resource in the area of the west of LiaoNing to the climatic area partition in the feasible plant area of chaoyang jujube, it completes special area partition of chaoyang jujube and guides the production and development of chaoyang jujube.
