科学地、充分地利用自然资源——气候资源是实现农业现代化的一个重要组成部分。本文着重讨论,如何发挥河池山区气候资源的优势,扬长避短,趋利避害等问题,从而加快山区农业现代化的进程。 一、河池山区气候资源 的长处和短处 河池山区地处广西西北部,云贵高原东南麓,属亚热带季风气候。其特点是,光、热气候资源丰富,全地区年太阳总辐射量90-108千卡/cm~2,生理辐射量46-55千卡/cm~2,全年平均日照时数1300—1700小时。全地区年平均气温17-21℃,日平均气温大于10℃的总积温,除南丹县在5100℃左右外,其余九县均在6000-7000℃之间。全地区夏季湿热,冬季温凉。最热月为七月,平均气温24.5～28.9℃。最冷月为一月,平均气温除南丹、罗城两县在7.5～9.0℃外,其余各县均在10～12.5℃之间。全地区无霜期长,南丹、罗城为300天左右,其余各县均在300天以上。
Scientific and full use of natural resources - climate resources is an important part of agricultural modernization. This article focuses on how to make full use of the advantages of climatic resources in Hechi mountain area and how to avoid weaknesses and avoid disadvantages so as to speed up the process of agricultural modernization in mountainous areas. First, Hechi mountain climate resources strengths and weaknesses Hechi mountain is located in northwestern Guangxi, Yunnan-Guizhou Plateau southeast foothills, is a subtropical monsoon climate. Its characteristics are rich in light and hot climate, the total annual solar radiation in the region 90-108 kcal / cm ~ 2, physiological radiation 46-55 kcal / cm ~ 2, the annual average sunshine hours 1300-1700 hour. The annual average temperature of the whole region is 17-21 ℃, and the daily average temperature is more than 10 ℃. Except for Nandan County at about 5100 ℃, the remaining nine counties are between 6000-7000 ℃. Summer hot and humid throughout the region, cool in winter. The hottest month for July, the average temperature of 24.5 ~ 28.9 ℃. The coldest month is January, with the exception of Nandan and Luocheng counties in the average temperature of 7.5 ~ 9.0 ℃, the remaining counties are between 10 ~ 12.5 ℃. Long frost-free period throughout the region, Nandan, Luo City for about 300 days, the remaining counties are in more than 300 days.
