四川省白河自然保护区川金丝猴生境评价

2005-2006年综合应用地理信息系统、全球定位系统、遥感技术对四川白河自然保护区内川金丝猴的栖息地进行监测评价.结果表明:在不考虑人为干扰的情况下,保护区内川金丝猴的最适宜栖息地面积为20.079 4 km2,占保护区总面积的12.39%;适宜栖息地面积为18.152 2 km2,占保护区总面积的11.20%;勉强适宜栖息地面积为64.439 3 km2,占保护区总面积的39.77%;不适宜栖息地面积为59.509 1 km2,占保护区总面积的36.72%.由于放牧、采药的影响,川金丝猴的适宜栖息地大面积丧失.在川金丝猴的实际栖息地内,最适宜栖息地面积为5.811 9 km2,仅占保护区总面积的3.59%;适宜栖息地面积为8.072 1 km2,占保护区总面积的4.98%;勉强适宜栖息地面积为46.920 4 km2,占保护区总面积的28.96%;而不适宜栖息地面积为101.235 6 km2,占保护区总面积的62.48%.

Habitat Evaluation for Sichuan Golden-Haired Monkeys in Baihe Nature Reserve in Sichuan Province

Between the year 2005 and 2006,the author monitored the habitant of golden-haired monkey with the geography information system,remote sensing and global position system in Baihe Nature Reserve in Sichuan Province.It showed that without the human disturbances,the most suitable habitat is 20.079 4 km^2,12.39% of the total area;the suitable habitat is 18.152 2 km^2,11.20% of the total area;the less suitable habitat is 64.439 3 km^2,39.77% of the total area;the unsuitable habitat is 59.509 1 km^2,36.72% of the total area.Influenced by human activities,the remaining habitat will be reduced.In this case,the most suitable habitat is 5.811 9 km^2,3.59% of the total area;the suitable habitat is 8.072 1 km^2,4.98% of the total area;the less suitable habitat is 46.920 4 km^2,28.96% of the total area;the unsuitable habitat is 101.235 6 km^2,62.48% of the total area.
