Refined Choice Analysis of Chinese-date Suitable Area in Chaoyang Area in Liaoning Province Based on GIS |
|
| Abstract: | Objective] The aim was to establish the refined choice index system for Chinese-date suitable area.Method] Combining all kinds of geographic information data with meteorological elements,the Chinese-date suitable area in Chaoyang area in Liaoning Province was determined based on the GIS by the refinement simulation method.Result] The Chaoyang area was very suitable for developing the planting industry of Chinese-date.The most suitable planting area of Chinese-date mainly distributed in the low altitude area in the Dalinghe and Xiaolinghe River basin.The annual mean temperature of this area was above 7.7 ℃,the annual precipitation was 460-530 mm,and the sunshine hours was 2 790-2 850 h.The climate condition and geographical condition in this area were all suitable for planting Chinese-date.Chinese-date had lower probability of freeze injury in winter with high yield and good quality.Conclusion] The research provided the scientific reference for improving the production ability of Chinese-date in Chaoyang area with high-yield,good quality,high efficiency and reasonable layout. |
