【摘要】：金絲猴是神農(nóng)架自然保護區(qū)的重要保護對象,基于生境在影響金絲猴生存和發(fā)展過程中的關鍵作用,以及目前神農(nóng)架金絲猴所面臨的適宜生境斑塊間日趨破碎化、猴群間隔離等問題,本文在對神農(nóng)架自然保護區(qū)金絲猴生境實地調(diào)查的基礎上,結(jié)合保護區(qū)相關基礎數(shù)據(jù)資料,以神農(nóng)架自然保護區(qū)金絲猴棲息地生境為研究對象,利用3S技術對神農(nóng)架保護區(qū)金絲猴棲息地生境破碎化現(xiàn)狀進行評價,同時利用最小費用模型識別了保護區(qū)金絲猴現(xiàn)有生境斑塊間的潛在生境廊道,篩選合適的廊道植物配置模式,進而提出生境廊道構建技術,優(yōu)化金絲猴生境格局。主要結(jié)果有:(1)利用景觀格局指數(shù)方法對生境景觀結(jié)構破碎化分析表明:神農(nóng)架自然保護區(qū)適宜森林景觀主要以大斑塊形式存在,占研究區(qū)面積的比例為64.5%,其他非林景觀總面積約占研究區(qū)面積的10%,主要以小斑塊形式分散分布為主,對金絲猴棲息地生境景觀的破碎化起著重要的作用,且這種規(guī)律在保護區(qū)金絲猴分布區(qū)比非分布區(qū)更加明顯。棲息地內(nèi)各景觀類型的斑塊形狀都比較復雜,斑塊分布比較離散,景觀連接度低,表明研究區(qū)各類景觀存在一定程度的破碎化現(xiàn)象。且保護區(qū)金絲猴非活動區(qū)的各類景觀斑塊比金絲猴活動區(qū)的各景觀類型的斑塊具有更為復雜的斑塊形狀、更加離散的分布狀態(tài)、較小聚合度、較大邊緣密度、較低的景觀連接度以及各類景觀整體在數(shù)目面積上更加不均衡的分布狀態(tài),說明神農(nóng)架保護區(qū)金絲猴非活動區(qū)各景觀類型的破碎化程度比活動區(qū)高。(2)基于生境可利用的景觀連接度分析方法對生境景觀的功能破碎化分析表明:研究區(qū)幾個大型的適宜生境斑塊間由于地形因素(海拔)、人為干擾(道路)等原因是導致神農(nóng)架金絲猴適宜生境破碎化的主要原因。神農(nóng)架金絲猴活動區(qū)和非活動區(qū)適宜生境斑塊間景觀的連接度連指數(shù)值普遍偏低,說明保護區(qū)金絲猴生境整體上均存在相當程度的破碎化,且非活動區(qū)和整個保護區(qū)適宜生境斑塊間的破碎化程度比活動區(qū)嚴重。(3)在神農(nóng)架金絲生境破碎化的現(xiàn)狀評價的基礎上,對神農(nóng)架金絲猴棲息地潛在生境廊道的構建研究表明:神農(nóng)架保護區(qū)現(xiàn)存4個面積較大的金絲猴“源”生境斑塊�；谶@4個生境“源”斑塊,利用最小費用距離模型,識別出4條金絲猴潛在生境廊道,可以將神農(nóng)架保護區(qū)現(xiàn)有的金絲猴適宜生境斑塊系統(tǒng)的聯(lián)系在一起,促進神農(nóng)架金絲猴對適宜生境的有效利用。利用實際調(diào)查統(tǒng)計的神農(nóng)架金絲猴適宜生境的植被群落結(jié)構,篩選出8種神農(nóng)架金絲猴生境廊道植物配置模式,根據(jù)實際的廊道分布地理環(huán)境以及相應植物物種的生態(tài)習性,確定了神農(nóng)架金絲猴生境廊道具體的植物配置模式,可用于進行神農(nóng)架金絲猴生境廊道的構建。
[Abstract]:Golden monkey is an important protection object in Shennongjia Nature Reserve. Based on the key role of habitat in affecting the survival and development of Golden Monkey, and the fragmentation of suitable habitat patches faced by Shennongjia Golden Monkey at present, On the basis of the field investigation of the habitat of golden monkey in Shennongjia Nature Reserve, this paper takes the habitat of Golden Monkey in Shennongjia Nature Reserve as the research object, combining with the basic data of the reserve, and taking the habitat of golden monkey in Shennongjia Nature Reserve as the research object. The habitat fragmentation of golden monkey in Shennongjia protected area was evaluated by using 3s technology, and the potential habitat corridor between the existing habitat patches of golden monkey was identified by using the minimum cost model. The appropriate plant allocation model of corridor was selected, and the construction technology of habitat corridor was put forward to optimize the habitat pattern of golden monkey. The main results are as follows: (1) the analysis of landscape structure fragmentation by using landscape pattern index method shows that the suitable forest landscape of Shennongjia Nature Reserve mainly exists in the form of large patches. The proportion of the area in the study area is 64.5%, the total area of other non-forest landscape is about 10 parts of the study area, mainly distributed in the form of small patches, which plays an important role in the fragmentation of habitat landscape of golden monkey. And this rule is more obvious in the protected area than in the non-distribution area. The patch shape of each landscape type in the habitat is complex, the patch distribution is discrete, and the landscape connectivity is low, which indicates that there exists a certain degree of fragmentation in all kinds of landscape in the study area. Moreover, all kinds of landscape patches in the inactive area of golden monkey in the reserve have more complex patch shape, more discrete distribution, smaller degree of aggregation and larger edge density than those in the active area of golden monkey. The lower degree of landscape connectivity and the more uneven distribution of the number and area of all types of landscape, The results show that the degree of fragmentation of each landscape type in the non-active area of Golden Monkey in Shennongjia Reserve is higher than that in active area. (2) the functional fragmentation analysis of habitat landscape based on the landscape connectivity analysis method available in habitat shows that: several parts of the study area are in the study area. The main reasons for the fragmentation of the suitable habitat of the Shennongjia Golden Monkey were the topographic factors (altitude) and human disturbance (road) among the large suitable habitat patches. The connectivity index between the suitable habitat patches in the active and inactive areas of Shennongjia Golden Monkey was generally low, which indicated that there was a considerable degree of fragmentation in the whole habitat of Golden Monkey in Shennongjia. And the fragmentation degree between the suitable habitat patches in the inactive area and the whole protected area is more serious than that in the active area. (3) based on the evaluation of the current situation of the fragmentation of gold silk habitat in Shennongjia, The study on the construction of potential habitat corridors of Shennongjia golden monkey habitat shows that there are four large "source" habitat patches in Shennongjia protected area. Based on these four habitat "source" patches and using the minimum cost distance model, four potential habitat corridors of the golden monkey can be identified, which can link the existing habitat patch system of the golden monkey in Shennongjia Reserve. To promote the Shennongjia Golden Monkey to the effective use of suitable habitats. Based on the vegetation community structure of Shennongjia golden monkey suitable for habitat, eight plant allocation models of Shennongjia golden monkey habitat corridor were selected. According to the actual corridor distribution geographical environment and the ecological habits of the corresponding plant species, 8 species of Shennongjia golden monkey were selected. The plant configuration model of the habitat corridor of Shennongjia Golden Monkey was determined, which can be used to construct the habitat corridor of Shennongjia Golden Monkey.
