【摘要】：哈尼稻作梯田系統(tǒng)作為全球重要農(nóng)業(yè)文化遺產(chǎn)(GIAHS),具有極高的生態(tài)、經(jīng)濟(jì)、文化價(jià)值。近年來(lái),以糧食產(chǎn)量增長(zhǎng)為導(dǎo)向的農(nóng)耕技術(shù)和作物品種單一化趨勢(shì),給哈尼梯田地區(qū)帶來(lái)了嚴(yán)重的生態(tài)和食品安全問(wèn)題。論文以農(nóng)戶生產(chǎn)行為作為切入點(diǎn),從主要糧食作物的經(jīng)濟(jì)效益、耕地資源特征、村落發(fā)展類型、農(nóng)戶的家庭特征與資源稟賦進(jìn)行實(shí)證研究,分析了哈尼梯田地區(qū)農(nóng)戶糧食作物種植結(jié)構(gòu)現(xiàn)狀及驅(qū)動(dòng)因素。結(jié)果表明:1)調(diào)查涉及的41.23 hm~2有效耕地中,按種植總面積排序,雜交稻、玉米、水果類作物位居前三。2)本地傳統(tǒng)糧食作物——梯田紅米,種植總面積和戶均種植面積遠(yuǎn)小于經(jīng)濟(jì)效益較高的雜交稻和兼有飼料用途的玉米。同時(shí),農(nóng)戶傾向于將其種植在質(zhì)量較差、海拔較高的耕地上。3)作物的經(jīng)濟(jì)效益和耕地海拔及質(zhì)量對(duì)替代性作物(如雜交稻和紅米)的種植選擇影響較大;個(gè)體農(nóng)戶層面上,農(nóng)戶特征與資源稟賦在不同程度上對(duì)不同作物的種植選擇產(chǎn)生影響。
[Abstract]:As an important agricultural cultural heritage in the world, Hani rice terrace system has a high ecological, economic and cultural value in recent years. The agricultural techniques and the trend of single crop varieties based on grain yield increase have brought serious ecological and food safety problems to the Hani terraced area. The paper takes the production behavior of farmers as the starting point. From the main economic benefits of food crops, cultivated land resources characteristics, village development type, household characteristics and resource endowment of farmers to carry out empirical research. The present situation and driving factors of grain crop planting structure of farmers in Hani terraced area were analyzed. The results showed that the cultivated land of 41.23 hm~2 was investigated in the order of total planting area and hybrid rice. Maize, fruit crops ranked first 3. 2) the local traditional food crop-terrace red rice, the total planting area and household planting area is much smaller than the high economic benefit of hybrid rice and both feed corn. At the same time. Farmers tend to plant it on cultivated land with poor quality and high altitude. The economic benefits of crops and the elevation and quality of cultivated land have a great influence on the planting choice of alternative crops (such as hybrid rice and red rice). At the level of individual farmers, the characteristics of farmers and resource endowments affect the planting choices of different crops to different extent.
