摘要:

近年来,在全球变暖的大背景下,西北也经历着同样的变暖趋势,尤其在西北干旱区新疆、甘肃河西走廊等地的棉花种植区,气候变暖对棉花生长发育的影响研究日益增多,但如何正确、合理地评价棉花对气候变暖的响应,已成为目前十分突出的科学和实际问题。在评价的过程中,评价指标的选择和确定是重中之重。鉴于此,本文筛选了几类重要的评价指标,主要有棉花生长发育、产量品质、种植结构、地理分布、农业气象灾害、农业病虫害气象指标等,这些指标的选择为科学评价棉花对气候变化的响应奠定了一定的基础。

Abstract:

With the globalwarming, climate in northwest China is experiencing the same change in recent years, especially in cotton planting region: Xinjiang and Gansu Hexi Corridor. More and more studies aimed on the impact of climate change on cotton growth and yields. However, it ismore important to reasonably assess the impact of climate change on crop. Furthermore, the selecting of assessment index ismost important in the p rocess of estimation. So we have selected some importantmeteorological indices for cotton growth and development, p lanting structure, geographical distribution, disaster of agriculturalmeteorology, diseases and pests of cotton, and all of these were the base of assessment for impact of climate change on cotton in northwest China.

Key words: arid region of northwest China, cotton, climate change, impact, assessment index
