行间生草对秦岭北麓猕猴桃园土壤养分及pH的影响

[目的]通过对秦岭地区猕猴桃园进行行间生草,来探讨多年生草对土壤pH、有机质及养分的影响。[方法]在西安猕猴桃试验站4年生的海沃德种植园,设置间作黑麦草、三叶草和林间组合,以自然生草为对照,于种植后第1、第2和第3年萌芽期分别测定果园不同土层的土壤pH、有机质、全氮、全磷、全钾、速效磷、速效钾含量的变化,并采用方差分析对数据进行分析。[结果]随着生草年限的递增,通过生不同的草种,土壤中全氮、有机质含量整体呈递增趋势;当生草年限达到3年时,随着土壤深度的增加,土壤中速效磷、速效钾含量逐渐降低;随着生草年限的递增,不同土层中自然生草的pH先增加后降低,三叶草的pH先降低后增加,黑麦草和林间组合的pH逐渐降低。[结论]在猕猴桃园生草能改良土壤养分状况,提高土壤有机质含量调节土壤pH。不同草种对土壤pH的影响不同,行间生林间组合和黑麦草能够改良北方的盐碱地。     

秦岭火地塘林区景观格局破碎度分析

秦岭火地塘林区原生森林景观曾因森林主伐遭到严重破环，经过20多年的恢复，到1988年该地区基本形成以次生天然林和人工林为主的森林景观格局。利用该地区1988年森林资源二类调查资料，对天然及人工干预形成的火地塘林区景观格局破碎化程度进行了分析。结果表明：天然林的破碎化程度比人工林低，并且主要林分破碎度明显低于其它林分，同样外界干扰下，树种的生长习性决定其破碎化程度。     

基于“点”、“线”体系的城市公共开放空间景观设计研究

Landscape Pattern Optimization of Chengdu Based on Modern Garden City

TOptimization of regional landscape pattern is significant for improving function and value of ecosystem,and restraining the expansion of urban layout.Taking Chengdu City for example,this paper applied RS and GIS techniques,landscape indexes and ecological service function evaluation to further analyze the temporal and spatial characteristics of landscape pattern and spatial differences of regional ecological functions,and on this basis,identified the spatial distribution of ecological source lands.Based on the long-term objective of building Chengdu into a modem garden city,this paper applied the accumulative cost distance model and introduced garden city theory to construct regional ecological corridors and ecological nodes,and explored the approaches of optimizing landscape pattern of modem garden city.The results showed that a great deal of arable land has been transferred to construction land in the urbanization;intensity of regional ecological functions showed obvious spatial differences;ecological source lands were mainly distributed in the Longmen Mountain,the Qionglai Mountain,the Changqiu Mountain and the Longquan Mountain;according to actual conditions of the study area,the road ecological corridors,river corridors and agricultural corridors in the layout of four rings and six radial corridors were constructed;ecological nodes dominated by intersection,wetland and forest park were formed.This research method and results are significant references for building Chengdu into a modem garden city
