title: 30 m resolution land cover data set in the krulun River Basin (1990)
title: 克鲁伦河流域30 m分辨率土地覆被数据集（1990年）

description: a. Data content (data file/table name, observation index content included)
This data includes the 30m resolution land cover data set of the krulun River Basin, which reflects the distribution of land cover types in the krulun River Basin and provides data support for land use planning in the krulun River Basin.
b. Construction purpose
The krulun River, known as the "mother river of the Mongols", has always been a good pasture for nomads to move to by water and grass. The rapid growth of population and the sharp increase of livestock, deforestation, overgrazing of grassland, and indiscriminate cultivation of sloping land have increased runoff after the rain, aggravated soil and water loss, reduced soil water storage capacity, intensified evaporation, and formed a certain range of water condition loss, which will affect the precipitation in the region, thus forming a vicious circle, further worsening the vegetation growth conditions and water storage capacity. With the temperature rising, precipitation decreasing, evaporation increasing warming and drying, as well as some unreasonable human economic activities, resulting in the shortage of water resources and the deterioration of the ecological environment in the krulun River Basin. As a tributary of Heilongjiang, the ecological and environmental problems of the krulun River can not be ignored. Therefore, it is very necessary to use remote sensing technology to dynamically monitor the krulun river basin to improve and protect the environment of the krulun River Basin.
c. Service object
It can widely serve scientific researchers in land use planning, ecological monitoring and other related disciplines.
d. Time range of data
1990
e. Spatial range of data
Krulun River Basin
f. Projection mode of data
Projected Coordinate System：Krasovsky_1940_Albers
Geographic Coordinate System：GCS_Krasovsky_1940
g. Subject scope of data
Biology&gt;ecology&gt;Regional Ecology
h. Amount of data
The total data volume is about 361.83mb
