【摘要】：山區(qū)聚落生態(tài)位反映聚落在山地垂直方向上所處的空間位置及人類生活所能利用的資源空間,是當(dāng)?shù)鼐用耖L(zhǎng)期適應(yīng)山地自然環(huán)境的結(jié)果。基于岷江上游各民族山區(qū)聚落生態(tài)位和氣象、社會(huì)、地形驅(qū)動(dòng)因子的空間分布,借助冗余分析,構(gòu)建山區(qū)聚落生態(tài)位地理特征與驅(qū)動(dòng)因子間的多水平貝葉斯模型,定量刻畫聚落生態(tài)位的民族屬性對(duì)山區(qū)聚落生態(tài)位地理特征與驅(qū)動(dòng)因子間關(guān)系的影響。結(jié)果表明:(1)影響研究區(qū)域內(nèi)1 667個(gè)與各民族聚落生態(tài)位地理特征的驅(qū)動(dòng)因子有顯著差異,海拔和坡度對(duì)前者影響較大,海拔、坡度、干季和濕季濕度、距河流距離對(duì)后者影響較大,且海拔對(duì)兩者的影響程度都最大,海拔和坡度地形驅(qū)動(dòng)因子與干、濕季濕度和距河流距離間的相關(guān)性較弱。(2)干、濕季濕度氣象驅(qū)動(dòng)因子對(duì)藏-羌聚落生態(tài)位地理特征影響較大,距河流距離和距縣城距離社會(huì)驅(qū)動(dòng)因子、海拔和坡度地形驅(qū)動(dòng)因子對(duì)藏族聚落生態(tài)位地理特征影響較大,這與藏族聚落生態(tài)位的分布面積和個(gè)數(shù)有關(guān)。(3)民族類型對(duì)聚落生態(tài)位地理特征指標(biāo)與氣象因子干季濕度間關(guān)系的影響最大,對(duì)聚落生態(tài)位地理特征指標(biāo)與地形因子坡度間關(guān)系的影響最小。岷江上游山區(qū)聚落生態(tài)位地理特征與驅(qū)動(dòng)因子間關(guān)系的研究,為量化山區(qū)聚落生態(tài)位與山地環(huán)境的關(guān)系提供了有效的數(shù)據(jù)支撐。
[Abstract]:Mountain settlement niche reflects the location of settlements in the vertical direction of mountains and the resources space that human life can use, which is the result of local residents' long-term adaptation to mountain natural environment. The distribution of various nationalities of Minjiang River mountain settlement ecological niche and the weather, terrain, social driving factors based on the spatial redundancy by means of analysis, construction of mountain settlements niche geographical characteristics and driving factors of the hierarchical Bayesian model, describe the influence the settlement of niche of national properties and driving factors of the relationship between mountainous settlements niche geographical features. The results showed that: (1) effects of driving factors in the study area and 1667 ethnic settlements niche geographical features have significant difference, altitude and slope have great influence on the former, altitude, slope, dry and wet seasons and humidity, the distance from the river has great influence on the latter, and the influence of altitude on both the maximum altitude. The terrain and slope and driving factors of dry and wet season from humidity and correlation between the distance from the river. (2) in dry and wet season humidity weather driven factors affect Tibetan Qiang settlements niche geographical features, the distance from the river and the distance from the county social driving factors, altitude and slope terrain driving factors have great influence on the Tibetan settlements niche geographical features, and the Tibetan settlements niche distribution area and the number of. (3) the effect of national type of settlement niche geographic feature index and meteorological factors in the relationship between the maximum humidity, impact on the slope settlement niche geographical characteristics index and the relationship between the minimum terrain factor. The relationship between geographical location and driving factors of mountain settlements in the upper reaches of Minjiang River provides effective data support for quantifying the relationship between mountain settlement niche and mountain environment.
