岷江上游地区生境适宜性评价数据集

生境适宜性评价可以有效揭示区域生境质量，是生态恢复与管理的重要基础。作者以岷江上游（北纬31度26分-北纬33度16分，东经102度59分-东经104度14分）为研究区域，在ArcGIS软件平台下，基于ASTERGDEM数据、前人研究成果和实地勘察数据，研发了该区域系列生境要素数据集。数据集包括五个方面：（1）地形地貌数据，包括：海拔高程数据、地形坡度数据、坡向数据；（2）气象气候数据，包括：区域年降雨量、旱季和雨季的平均温度、太阳日照时数、蒸发量和相对湿度；（3）土壤类型数据；（4）植被类型数据；（5）生境适宜性指数和生境适宜性评价等级数据。该数据集存储为.tif格式，压缩后数据量为4.57MB。该数据集的分析研究成果发表在《JournalofMountainScience》2015年12卷第3期。

Habitat suitability assessment can effectively reveal regional habitat quality and serves as an important foundation for ecological restoration and management. The authors took the upper reaches of the Minjiang River (31°26' N - 33°16' N, 102°59' E - 104°14' E) as the study area, and developed a series of habitat factor datasets for this region on the ArcGIS software platform based on ASTER GDEM data, previous research results and field survey data. The dataset includes five aspects:
1. Topographic and geomorphic data, including elevation data, terrain slope data and aspect data;
2. Meteorological and climatic data, including regional annual rainfall, average temperatures in dry and rainy seasons, solar sunshine duration, evaporation and relative humidity;
3. Soil type data;
4. Vegetation type data;
5. Habitat suitability index and habitat suitability assessment grade data.
This dataset is stored in .tif format, with a compressed data size of 4.57 MB. The research findings derived from this dataset were published in *Journal of Mountain Science*, Volume 12, Issue 3, 2015.
