不同等級(jí)石漠化綜合治理的小氣候效應(yīng)-以貴州省花江峽谷為例
摘要: 對(duì)貴州省花江峽谷區(qū)12個(gè)石漠化樣地小氣候進(jìn)行觀測(cè)和研究.結(jié)果表明,隨著石漠化綜合治理時(shí)間延長(zhǎng),植被結(jié)構(gòu)得到改善,小氣候效應(yīng)逐漸凸現(xiàn):不同等級(jí)石漠化樣地林下平均氣溫及土壤溫度在濕熱季節(jié)得到有效降低,而在干冷季節(jié)略顯升高;空氣相對(duì)濕度在年際同期水平顯著提高;林下光照強(qiáng)度逐漸減弱.生態(tài)系統(tǒng)結(jié)構(gòu)的改善,使得系統(tǒng)開(kāi)放性降低,能量散失減少,生態(tài)環(huán)境朝著良性有序方向發(fā)展. Abstract: In this paper microclimate was observed and studied in 12 plots under different rocky desertification degrees in the Huajiang Gorge Area of Guizhou. Results showed that architecture of vegetation and effects of microclimate have been improved with changing comprehensive treatment time: air temperature and soil temperature fall efficaciously in wet-hot season but have been improved appreciably in dry-cold season. Relative air humidity is improved obviously with the same season in different years. Intensity of illumination tends to weaken bit by bit. Ecosystem structure that has been improved efficaciously makes openness of the ecosystem to fall and energy to lessen. Quality and function of the entironment have been improved in a proper way. 作 者: 吳克華 熊康寧 李坡 龍明忠 曲明昕 WU Ke-hua XIONG Kang-ning LI Po LONG Ming-zhong QU Ming-xin 作者單位: 吳克華,李坡,WU Ke-hua,LI Po(貴州科學(xué)院喀斯特資源環(huán)境與發(fā)展研究中心,貴陽(yáng),550001)熊康寧,XIONG Kang-ning(貴州師范大學(xué)中國(guó)南方喀斯特研究院,貴陽(yáng),550001)
