| Abstract: |
| Rural areas play an important role in the construction of ecological civilization under
the background of rural revitalization. In China, the evaluation of eco-environmental quality of
villages and towns started late, and most of the related studies applied the evaluation model of
large-scale areas such as cities, lacking the evaluation method and system of eco-environmental
quality of villages and towns. Meanwhile, with the advancement of science and technology, the
disadvantages of traditional ecological environment evaluation methods are gradually emerging,
including long evaluation cycle, numerous evaluation indicators, difficult data acquisition, lack
of residents’ participation, and so on. In response to the above problems, through the integration
of subjective and objective perception means such as remote sensing, sensor sensing and human
sensing, which realizes the spatial-temporal complementarity and attribute complementarity
of the three perception means, it constructed a comprehensive evaluation system of ecological
environment quality of villages and towns by integrating multiple perceptions. A case study
and analysis in depth on the evaluation of ecological environment quality were then carried out
in villages and towns of Jizhou District, Tianjin City, China.
For remote sensing, Landsat 8 multispectral images were used to calculate the four
indicators for greenness, moiture, dryness and heat of Jizhou District. Then the remote sensing
ecological index (RSEI) was aggregated based on these four indicators. The sensor sensing
ecological index is based on the sensor monitoring data of the air quality monitoring stations
released by the ecological environment departments of the cities surrounding Jizhou District,
and integrates the multi-source data such as land use, points of interest, night light and digital
elevation model to build an air quality land use regression model, which simulates the spatial
distribution of nitrogen dioxide in Jizhou district. Based on the Internet platform, it put and
collected questionnaires in various administrative villages in Jizhou District, and obtained
the perception of the villagers in Jizhou District on the quality of the ecological environment
and the level of pollution discharge, as well as the overall satisfaction with the ecological
environment. The township eco-environment index obtained by the above three sensing means
was further summarized according to the administrative boundary of the township, and acomprehensive index of the township eco-environment integrating multi perception was constructed.
The results of remote sensing showed that the areas with better eco-environmental quality are concentrated in the northern mountain forest
area, the southern farmland, paddy field, reservoir and flood discharge area of Jizhou District. The eco-environmental quality of the populated
villages and towns in the middle was relatively poor, especially around the reservoir (such as Yuyang Town). The results of sensor sensing showed
that the air quality of villages and towns in Jizhou District was good according to the national air quality standard. The overall NO 2 pollution
situation in the 26 townships of Jizhou District in 2020 was relatively mild, and the annual average concentration of NO 2 in each township was not
seen to exceed the standard. The results of human sensing showed that most of the residents in Jizhou District were satisfied with the surrounding
ecological environment. The perceived ecological environment quality, perceived pollution emission and eco-environment satisfaction in general
were higher in the mountainous areas north of Yuyang Town and around Yuqiao Rreservoir than in the townships in the south of Jizhou District.
Generally, the multi-perception index of each township shows a trend of gradually increasing from the center of Yinliu Town and Yuyang
Town to the outside. At the same time, the evaluation results of subjective and objective perception of each township are not consistent in spatial
distribution. This distribution trend is related to the distribution of population activities and industries in each township of Jizhou District. The
central area, such as Yuyang Town, although the objective remote sensing index and sensor sensing index of the ecological environment are relatively
low, the environmental satisfaction is relatively high, probably due to the relatively better ecological environment infrastructure, and vice versa;
while the southern area, although the objective perceived ecological environment is relatively good, the level of economic development is relatively
low and the environmental infrastructure may not be comparable to that in the central region, resulting in relatively low satisfaction. It is necessary
to improve the residents' satisfaction with the ecological environment while improving the quality of the ecological environment.
Compared with the single perception method, the multi-perception integration eco-environmental quality evaluation system can achieve
rapid, comprehensive and scientific eco-environmental quality evaluation of villages and towns, which can not only provide a scientific basis for
the ecological planning and construction of the relevant departments of local villages and towns, but also provide references for improving and
maintaining a good village and town living environment and ecological environment in the future. It is also of great significance to promote the
sustainable development of villages and towns and the construction of ecological civilization. Meanwhile, it can provide a new perspective and
scientific support for eco-environmental quality monitoring and evaluation of villages and towns in China. |
