广西石山地区气候资源评价及其绿化后对气候的影响

THE EVALUTION ON GUANGXI KARST REGION CLIMATE RESOURCES AND THE EFFECT ON CLIMATE AFTER AFFORESTATION

摘要:

本文主要研究广西石山地区气候资源的分布状况,探讨植树绿化对石山地区的气候、地表水份平衡以及农业生态系统的影响,从气候的角度提出石山地区综合治理的基本模式和途径。
文中比较详细地分析了石山地区光、热、水、干旱、洪涝等气候因素的时空变化特征,估算了石山地区气候-土壤生产潜力,为石山地区综合治理和开发提供有关气候源方面的资料和依据。
文中还建立了一个土壤-植物-大气模型。利用该模型,对绿化后可能造成的气候和水份平衡的变化进行了估算。该模型对农业气象学、水文学等领域中的许多问题均有应用价值。

Abstract:

This paper mainly deals with the distribution of Guangxi Karst region climate resources,probes into the effect on Karst regional climate, water balance on the earth surface and agricultural eco-system over the land after afforestation.And from the climatological point of view,the author also puts forward the basic model and avenues on karst regional comprehensive harness.
Minutely this paper analyses the change characteristics of time and Space of climate factors in Karat region(e.g.sunlight,heat,water resources, aridity,flood etc),estimates the productive potentialities of Karat regional climate-soil system.These provide materials and basis on climate for Karst region comprehensive harness and development.
A soil-plant-atmosphere model is also established in the paper.Using the model the author estimates the effects on the climate and water balance in the area after afforestation.The model is applicable to the problems in a large range of agricultural meteorology and hydrology etc.
