A key challenge to the sustainability and security of grassland capacity is the protection of water-related ecosystem services (WESs). With the change of land use, the supply of aquatic ecosystem services has changed, and the grassland-carrying capacity has been affected. However, the correlation mechanism between WESs and the grassland-carrying capacity is not clear. In this study, we used the InVEST(Integrated Valuation of Ecosystem Services and Tradeoffs) model to evaluate the impact of land-use change on WESs, and made a tradeoff analysis between WESs and grassland-carrying capacity. Considering that the Heihe River Basin (HRB) was an important grassland vegetation zone, which was a milestone for the development of animal husbandry in China, HRB was taken as a case. The main findings are as follows: (1) the spatial distribution of WESs shows the dissimilation rule, the upper reaches are the main water yield area, the soil retention is weakening in the middle and lower reaches, and the pollution has further increased in the middle and upper reaches. (2) The carrying capacity of animal husbandry decreased in the upper reaches, increased in Shandan County and Zhangye City in the middle reaches, and decreased sharply in other regions. (3) There was a positive correlation between the livestock-carrying capacity and nitrogen export in 2018, which was increasing. As the change of land use has changed the evapotranspiration structure, WESs have undergone irreversible changes. Meanwhile, the development of large-scale irrigated farmland and human activities would be the source of a further intensification of regional soil erosion and water pollution. Therefore, it is necessary to trade off the WESs and animal husbandry under land-use change. This paper revealed how WESs changed from 2000 to 2018, the characteristics of the changes in the spatial and temporal distribution, and the carrying capacity. It aims to provide a scientific basis for coordinating the contradiction between grassland and livestock resources, improving the regional ecological security situation, and carrying out ecosystem management.

The conflict between economic development and environmental protection has become increasingly prominent in the urbanization process of the Yangtze River urban agglomeration, the most economically developed region in Jiangsu Province in China. In order to investigate the sustainable development status, and thus provide decision support for the sustainable development of this region, the ecological footprint model was utilized to evaluate and analyze the ecological footprint per capita, the ecological carrying capacity per capita, and the ecological deficit per capita for the period from 2013 to 2017. Furthermore, the Grey model is employed to predict the development trend of the ecological footprint for 2018 to 2022. The evaluation results show that the ecological footprint per capita has been increasing year by year since 2013, reaching a peak of 2.3897 hm2 in 2015 before declining again. In the same period, the available ecological carrying capacity per capita and the ecological footprint per capita basically developed in the same direction, resulting in an ecological deficit per capita and gradually increasing from 2013 to a peak of 2.0303 hm2 in 2015 before declining. It is also found that the change of ecological carrying capacity is not substantial, and the change of the ecological deficit is mainly caused by a huge change of the ecological footprint. The forecast results show that the ecological deficit per capita will reach 1.1713 hm2 in 2018, which will be another deficit peak after 2015. However, in the later period until 2022, the ecological deficit per capita will begin to decline year by year. These results can provide effective inspirations for reducing the ecological deficit of the Yangtze River urban agglomeration, thus promoting the coordinated development of the economy and environment in this area.

Based on GIS and RS technology, this paper analyzed the land use change in Da'an city from 1995 to 2010. land-use ecological evaluation index was constructed to evaluate the land-use ecological risk of Da 'an city dynamically, and the land-use ecological risk level map was made, and then the distribution and change of the land-use ecological carrying capacity pattern of Da'an city were analyzed qualitatively. According to the evaluation results of ecological carrying capacity, the ecological environment of Da'an city has deteriorated in fifteen years. in 1995, the poor ecological environment area is mainly distributed in the northeast area of Da'an city, and the area is small, while the area of the central and southern areas is large; In 2010, the western region also appeared environmental degradation, the northeast environment deterioration is serious, the dominant area is reduced, and a small amount of deterioration in the central and southern regions. According to the study of this paper, in the future, we should strengthen the comprehensive management of this part of the area, strengthen vegetation coverage, reduce soil erosion, ensure the effective improvement of ecological environment.

 AbstrakKabupaten Sukoharjo merupakan kota satelit yang memberi daya dukung bagi kota utamanya (Kota Solo). Pembangunan Kawasan Solo Baru dan Kartasuro sebagai kota satelit mandiri dengan konsep permukiman yang didukung oleh ketersediaan fasilitas penunjang akan berimbas pada perubahan pemanfaatan lahan. Kabupaten Sukoharjo sebagai salah satu lumbung beras nasional justru perlu diperhatikan dan dijaga. Keberadaan lahan pertanian (pangan) di Kabupaten Sukoharjo menjadi terancam oleh intensitas pembangunan kota yang mengarah pada alih fungsi lahan non terbangun (lahan pertanian) menjadi terbangun. Penelitian ini bertujuan: (1) menganalisis kebutuhan dan ketersediaan pangan, (2) menganalisis daya dukung (Carrying Capacity) lahan pertanian dalam mendukung ketahanan pangan, dan (3) melakukan estimasi kebutuhan lahan pertanian pangan di Kabupaten Sukoharjo. Sebesar 44,16% (20.617 ha) lahan di Sukoharjo diperuntukkan untuk sawah. Daya dukung pangan secara keseluruhan di Kabupaten Sukoharjo mampu tercukupi ditunjukkan dengan nilai 1,62 yang berarti bahwa kebutuhan pangan mampu dicukupi dengan luas lahan pertanian dan produksi padi yang dihasilkan saat ini. Kebutuhan lahan pertanian pangan berkelanjutan (KLP2B) menurut kecamatan di Kabupaten Sukoharjo yang masih belum dapat dipenuhi kebutuhan pangan di wilayahnya adalah Kecamatan Kartasura. Hingga 20 tahun ke depan (2031), KLP2B yang tinggi di Kabupaten Sukoharjo masih berada di Kecamatan Grogol, Kecamatan Kartosuro, Kecamatan Mojolaban dan Kecamatan Sukoharjo.Kata kunci: ketahanan pangan, daya dukung, pembangunan wilayah AbstractSukoharjo Regency is a satellite city that provides support for its main city (Solo City). The development of Solo Baru and Kartasuro areas as self-contained satellite cities with the concept of settlements supported by the availability of supporting facilities will impact on land use change. Sukoharjo Regency as one of the national rice granary precisely needs to be considered and maintained. The existence of agricultural land (food) in Sukoharjo Regency becomes threatened by the intensity of urban development that leads to the conversion of non-built land (agricultural land) to be built. This study aims to: (1) analyze the need and availability of food, (2) analyze the carrying capacity of agricultural land in supporting food security, and (3) estimate the needs of food agriculture land in Sukoharjo Regency. A total of 44.16% (20,617 ha) of land in Sukoharjo is reserved for rice fields. The food carrying capacity in Sukoharjo Regency as a whole is sufficiently indicated by a value of 1.62 which means that food needs can be satisfied with the existing area of agricultural land and rice production. The need for sustainable agricultural land (KLP2B) in Sukoharjo Regency that has not been fulfilled by the needs of food in its area is Kartasura District. Until the next 20 years (2031), high KLP2B in Sukoharjo Regency is still in Grogol District, Kartosuro District, Mojolaban District and Sukoharjo District.Keywords: food security, carrying capacity, regional development
