京津风沙源治理工程对种植结构的影响分析

The analysis of sample counties' plan structure affected by wind and sandstorm control project

京津风沙源治理工程是党中央、国务院决定启动实施的一项重点生态工程,文章通过对2006—2009年样本县的种植结构进行分析,结果表明:2006—2009年,京津风沙源治理工程农作物总播种面积、粮食播种面积和粮食总产量均在2008年达到最大,而粮食单产却在2008年最低。这主要受到工程区的环境条件、农户参与积极性、市场需求等的影响。

The wind and sand storm control project decided by Party Central Committee and State Council is the implementation of a key ecological project.The sample counties＇plant structure from 2006 to 2009 was analyzed in the paper.The result showed that：the total sown area of crops,the grain sown area and the total grain output were maximum in 2008,but the unit area grain yield was minimum. This was mainly influenced by environmental conditions in project area,the enthusiasm of farmers and the market demand.
