Chinese Abstract

根據氣象條件與玉米生長適應性的關係,將新疆玉米生長適應性評價、生態區的氣候資源評價與GIS技術相結合,研究了新疆玉米種植區生態資源的優劣,並進行綜合評價,判別在不同生態區域的玉米生長適應性及優勢因素,具有其理論價值和實踐意義,為玉米佈局、區域化、專業化生產提供決策依據。

English Abstract

Maize growing plays an important role in cereal production, animal husbandry, livestock and poultry breeding, industry, regulation of cropping systems, rotation of crops, enlargement of multiple cropping area, etc. in Xinjiang, the maize-growing area occupies 20%~30% of the total area under cultivation, and it is second only to the wheat-growing area. The maize-growing regions in Xinjiang are mainly in the Tarim Basin, Hami Basin, Yili River Valley, Bortala Mongol Autonomous Prefecture, Usu and Shawan counties of Tacheng Prefecture, Manas River Watershed, Changji Hui Autonomous Prefecture, some regions of Altay Prefecture, and all the farms of Xinjiang Group Company of Production and Construction. Xinjiang is characterized by vast lands, complicated terrains and great difference in climatic conditions, so the maize varieties and cropping systems are different from the different regions. In this paper, the advantages of climatic and ecological factors and the variety selection in the maize-growing regions in Xinjiang are analyzed using the means of GIS so as to fully utilize climatic resources, reduce natural disasters and reap high yield of maize. The results are as follows: (1) In Xinjiang some region are suitable to grow maize but some other regions are not; (2) By combining the evaluation models with GIS, the evaluation methods are developed for the climatic divisions of growing maize, and the management of attributive data and spatial data is achieved; (3) The rational distribution of maize- growing regions in Xinjiang is researched by superposing the evaluation map of climatic suitability to growing maize with the map of maize-growing distribution using the means of GIS; (4) GIS can not only used in evaluating climatic resources in the maize-growing regions in Xinjiang, but can also be used for growing other crops.
