Abstract:

To understand the climate change rules of irrigation area on agricultural production, the author analyzed the climate productivity change in oasis in the western region using the meteorological data in Gansu Hexi, South Xinjiang and Ningxia. The results showed that the change rule of climate productivity as: climate productivity was increasing year by year in Gansu Hexi and South Xinjiang region, the growth rate of 0.97~38.12 kg/(hm2?a), showed a decreasing trend in Ningxia region, deceleration was 4.65~17.86 kg/(hm2?a), and with the precipitation trend was very consistent. The climate productivity year by year was increasing in the areas of less than 90° longitude, with the increase of latitude and longitude; the climate productivity year by year was increasing in the areas of greater than 90° longitude, with latitude reducing and longitude increasing. For the 49 possible future situations, changing trends of climate productivity was as followed: the climate productivity with wet type of climate was most favorable growing trend, an increase of 3.4~28.5 kg/(hm2?a); climate productivity was a decreasing trend and decreased 6.6~29.9 kg/(hm2?a) with dry type of climate.
