太行山南麓焦作北山低山丘陵区生态建设研究

豫北太行山低山丘陵区属于强干扰、退化的土地生态系统。为了实现科学的豫北太行山低山丘陵区生态环境建设，在对豫北太行山地区自然因子植被、土壤、地形分异性和人为N子分异性研究的基础上，进行叠加分析。将北山生态系统，按照其生态功能结合自然、人为干扰现状分为山顶消费型、山坡地保护型、河沟地生产型和人工调和型。结果显示：北山地区生产型和消费型的面积比例分别为38．8％和24．9％；保护型和调和型为28．9％、7．4％，整个北山地区生产型和消费型面积过大，而调和型和保护型面积过小，表明豫北太行山低山丘陵区生态压力和人为干扰过大，处于一个不合理的利用状态。依据以上分析，并结合北山的实际现状，对北山的各种土地生态类型提出了相应的治理对策。图4，表2，参8。

Study on Ecological Construction of Jiaozuo,Beishan,South Slope Mt.Taihang Hill and Mound Region

Yubei Mt.Taihang hill and mound region belongs to a strong jamming, degenerated land ecosystem. In order to realize the ecological environment construction of Yubei Mt. Taihang hill and mound region, the variances of vegetation, soil and terrain in Yubei Mt. Taihang area are analyzed, and overlay analysis is done. According to its ecology function and the nature,jamming situation, the Beishan mountains ecosystem is divided into mountaintop consumption land type, brae protection land type, channel production land type and artificial mixed land type. The research results show that in the Beishan mountains region, the proportions of production land and consumption land are occupied 38.8% and 24.9 %, respectively. Protection land and mixed land are 28.9 % and 7.4 % respectively. In whole Beishan region, the production land and consumption land is oversized, and the mixed land and the protection area are very small, which indicated that the Yubei Mr. Taihang hill and mound region ecology pressure and the jamming are oversized, and under an unreasonable use condition. Base on above analysis and Beishan actual situation, the corresponding countermeasures of each kind of land ecology type in Jiaozuo, Beishan were proposed.
